I have sat in a lot of offices and boardrooms over thirty years in business, and the ones where people thrived almost always had the desks facing the right way. Eight Mansions feng shui is the system that explains why, and it is the school I teach beginners first because you can check every claim yourself with a compass.
What Eight Mansions Feng Shui Actually Is
Eight Mansions feng shui, called Ba Zhai in Chinese, is the school that sorts every building and every person into one of two clubs and then tells you which rooms of your own house are working for you and which ones are quietly working against you. The name comes from the eight trigrams of the bagua: each sitting direction of a building belongs to one trigram, and that trigram’s mansion determines how the other eight directions behave for the people inside. It is the most widely practiced school of feng shui in the world, and the one most people have used without knowing its name, because the phrase “your lucky direction” that travels through every culture’s folk wisdom is Eight Mansions arithmetic underneath.
What the school actually claims is modest, which is why I teach it and why I trust it. It claims that a building has a sitting trigram, that a person has a life trigram computed from birth year and sex, and that the interaction between the two produces a fixed map of eight sectors, four supportive and four draining, and that the map is stable. No annual updates, no flying stars to chase, no equipment to buy. You work out the map once, and it holds for as long as you live in that house. In a field crowded with schools that contradict each other, Eight Mansions is the one a skeptical person can verify with a compass, a floor plan, and one free afternoon.
I came to it the same way I came to everything in this tradition: through business, not mystery. A client in the recruitment years kept losing staff from one particular branch office, not to competitors but to burnout, and the exit interviews said the same strange thing: I cannot explain it, I just feel depleted there. I ran the numbers on a whim. The building sat Wu, the West group, and the department that kept resigning sat in the Jue Ming sector, the worst of the eight, which the school associates with exhaustion and attrition. I did not sell him a cure. I moved the department one floor down, into the Sheng Qi sector, which cost him a week of internal shuffling and nothing else. The resignations stopped that quarter. That is the kind of result that makes a businessman take a school seriously.
The One-Sentence Version, for the Reader in a Hurry
Every building sits in a trigram, every person belongs to a trigram, and together they sort your floor plan into four good sectors and four bad ones; sleep and work in the good ones, keep toilets, storage and machines in the bad ones, and you have done Eight Mansions. That sentence is the whole school, and everything else on this page is the reasoning, the arithmetic, the applications and the honest limits around it.
The reason I give you the one-sentence version so early is that feng shui has an industry problem: practitioners earn by mystifying, so the simplest workable system in the tradition gets dressed up as a lifetime of study. It is not. A motivated beginner can compute their own life trigram in five minutes and their whole apartment’s map in an hour, and the rest of this guide exists to make sure you do it correctly, because the one real trap in Eight Mansions is not complexity but sloppiness: taking the facing for the sitting, misreading the compass in a steel-framed building, or using the wrong birth year for people born in January. Those mistakes are worth a section each, and each has one.
Where Eight Mansions Sits Among the Schools
The feng shui family tree has two great branches. The Form School, called Xing Shi, reads the physical world: mountains, water, roads, the shape of the land and the building. The Compass School, called Li Qi, reads directions and time with instruments and arithmetic. Eight Mansions is the eldest practical child of the compass branch, and its siblings are Flying Star, San He, Xuan Kong Da Gua and the other timing schools. The clean division of labour, the one I use in professional audits, is this: Form tells you whether the location is fundamentally sound, Eight Mansions tells you which sectors of the building to use, and Flying Star tells you how the building’s luck shifts across its twenty-year periods. A serious practitioner uses all three layers. A homeowner with one afternoon can get the majority of the available benefit from Eight Mansions alone, which is exactly why this school is the right starting point and why I teach it first.
The school’s classical roots are unusually respectable. The life trigram method that assigns people to East and West groups traces to the Eight Wandering Stars logic in the classical corpus, and the sitting-direction method for houses is documented in the Ba Zhai Ming Jing, the Eight Mansions Bright Mirror, a text from the late imperial period. What that means in practice: the arithmetic you will learn on this page is the same arithmetic a Qing dynasty surveyor used, and it has not needed an update because directions and birth data have not changed. I like tools that do not need updates. My students notice I say this often, and it is a business instinct: a system that keeps changing its own rules is usually a system that never had any.
What Eight Mansions Can and Cannot Do
Before any technique on this page, the boundaries, stated the way I state them to clients. Eight Mansions can tell you which sectors of a building support rest, health, relationships and income for a given person, and which sectors drain them. It can rank directions for a desk, a bed, a door. It can tell you why one room of the house is where everyone fights and another is where everyone naps. It cannot diagnose illness, it cannot make a bad business good, it cannot replace a locked door with a lucky one, and it absolutely cannot substitute for medical, legal or financial professionals. Anyone who sells you the removal of misfortune, in instalments, is not practicing this school; they are practicing its abuse, and the abuse is what gave the whole tradition its superstition problem.
The second boundary is subtler and I owe it to you plainly: Eight Mansions is a strong half of a reading, not the whole reading. In my own practice it sits beside BaZi for the person, Qi Men Dun Jia for the dates, and Flying Star for the time layer of the building itself. When clients ask for a feng shui audit, the Eight Mansions map is usually the first deliverable because it is fast and stable, and the deeper layers follow if the question needs them. If you finish this page and apply it, you will know more about your own home than most of its previous owners ever did. If you then want the timing layer, the door and date selection, that is what the rest of this site is for, and the links are at the bottom.
A Note on How I Teach This
I run a business, and before that I ran several, and I have interviewed over ten thousand people across three decades in recruitment and staffing. That career gave me a habit that never left: I do not trust a claim I cannot check, and I do not teach a method I cannot demonstrate on a real case in front of a class. Everything in this guide follows that habit. Each rule comes with the arithmetic that produced it, each application comes from a real audit with the identifying details removed, and each limitation is stated before you can discover it yourself the expensive way. My students in Singapore and Kuala Lumpur hear the same opening line I will give you here: feng shui is a decision instrument, and the day it stops helping you decide is the day you should put it down.
Two practical notes for using this page. It is long, deliberately, because it is the complete reference and it is meant to outrank the thin listicles that dominate the search results, so use the table of contents and jump to your section if you are mid-project. And it links to the deeper pages on this site: the trigram reference, the five elements, the date selection method, the Qi Men Dun Jia layer that I use for the hour-level decisions. The library exists so this page can stay honest about its own scope, and every link is free, because that is the policy this whole site runs on.
The Eight Trigrams, the Real Foundation
Everything in Eight Mansions is built from the eight trigrams, so this is the one piece of theory the method genuinely requires, and I will give it to you the way I teach it in class, which is the engineering way rather than the mythology way. A trigram is a stack of three lines, each line broken, yin, or solid, yang. Eight stacks are possible: 222, which is Kun, three broken lines; 223 patterns of mixing, and so on up to Qian, three solid lines. The names, in the order the arithmetic uses them, are Qian, Dui, Li, Zhen, Xun, Kan, Gen and Kun. Each trigram carries four properties that Eight Mansions actually uses: a direction, an element, a family role, and a body association. The mythology around them is rich and I respect it, but the method runs on those four properties, so those are what this section delivers.
The direction assignments, because you will need them for the compass work later. Qian is the northwest, Dui the west, Li the south, Zhen the east, Xun the southeast, Kan the north, Gen the northeast and Kun the southwest. The elements: Qian and Dui are metal, Li is fire, Zhen and Xun are wood, Kan is water, Gen and Kun are earth. Learn these as pairs rather than eight isolated facts: two metals in the west and northwest, wood in the east and southeast, fire alone in the south, water alone in the north, two earths in the southwest and northeast. That pairing is not a memory trick, it is the actual structure, and the East and West groups you will meet in the next section fall out of it mechanically.
There is a classical ordering trick called the Later Heaven arrangement, the one where the trigrams sit around the compass in their directional homes, and an earlier one called the Early Heaven arrangement used in other divination systems. You only need the Later Heaven arrangement for this school, and you have effectively already read it in the paragraph above: the compass order around the wheel is Kan north, Gen northeast, Zhen east, Xun southeast, Li south, Kun southwest, Dui west, Qian northwest. If you want the deeper reference, this site has a full trigram guide written for the Qi Men Dun Jia system where the same eight characters appear as palaces, and the two pages reinforce each other nicely for learners who like seeing one symbol family from two angles.
The Two Groups, and Why They Exist
Here is the single most important structural fact in the whole school, and it is simpler than any book makes it look. Take the eight trigrams and divide them into two sets of four. The East group: Zhen, Xun, Li and Kan, wood, wood, fire and water, which feed each other in the generative cycle, wood making fire and water making wood. The West group: Qian, Dui, Gen and Kun, metal, metal, earth and earth, which likewise support each other, earth making metal. Inside each group, the elements are mutual friends. Between the groups, they are mutual strangers at best: East’s wood clashes West’s metal, West’s earth clashes East’s water, and East’s fire drains West’s metal while West’s metal cuts East’s wood in the other direction. The two groups are not good and bad; they are two chemistries, and the school’s entire logic is to keep a person’s trigram chemistry and the house’s trigram chemistry aligned.
So the rule that beginners hear and that this page will now make obvious: an East group person is supported by an East group house, a West group person by a West group house, and within either house, each of the eight sectors behaves differently for you depending on whether your personal trigram and that sector’s trigram belong to the same group. A person whose life trigram is Li, fire, sitting in a Kan, water, sector, is putting fire into the north’s water: that is a hostile combination inside the same group, which is why within-group does not mean uniformly good. The four supportive and four draining sectors are computed exactly from these elemental relationships, and if you can follow wood feeds fire, fire makes earth, earth makes metal, metal feeds water, water feeds wood, plus the control cycle where wood parts earth, earth dams water, water kills fire, fire melts metal, metal chops wood, then you can compute the entire Eight Wandering Stars table yourself without ever memorising it. I teach both routes: the memorisers get the table, the engineers get the cycles, and both arrive at the same floor plan.
Family Roles and the Folk Layer
Each trigram carries a family role from the classical corpus: Qian the father, Kun the mother, Zhen the eldest son, Kan the middle son, Gen the youngest son, Xun the eldest daughter, Li the middle daughter, Dui the youngest daughter. Some practitioners build a whole layer of interpretation on this, reading which family member is affected by which sector’s condition, and in honest hands it can be strikingly specific: a persistent Gen-sector bathroom in an otherwise fine house, for example, gets blamed in the classical literature for the youngest son’s stalled start in life. I treat the family layer the way I treat any soft claim: useful for reading a case after the fact, unreliable for prediction before it, and never a substitute for the hard layer of group, element and direction. When a client asks me whether the missing southwest corner is hurting the wife, my honest answer is that the house’s map matters more than the folklore, and that the remedy is the same either way: strengthen the sector with real structure, real use, real weight.
The body associations are worth one paragraph because they show up in every classical text and because they connect this school to Chinese medicine, which shares the five-element language. Li associates with the heart and eyes, Kan with kidneys and ears, Zhen with feet and nerves, Xun with thighs and wind-borne illness, Gen with hands and spine, Kun with the stomach and abdomen, Dui with mouth and lungs, Qian with the head. In a professional audit I use these as a checklist language for tendencies, never as diagnoses: a client sleeping long-term in a hostile Kan sector who reports poor sleep and lower back trouble gets a recommendation to try the Sheng Qi room for a month, and if the report is a genuine medical concern, the recommendation comes with the sentence you have heard me write before, the doctor keeps every decision that matters.
Reading Trigrams Without the Romance
A paragraph for the reader who, like me, came to this from a world of contracts and headcounts and has no patience for decorated language. The trigrams are eight three-bit binary codes. The direction assignments form a fixed lookup table. The element cycles form two 5-node directed graphs, generation and control, both closed, both deterministic. Eight Mansions computes a person code from birth year and sex via a fixed formula, computes a house code from sitting direction via a fixed lookup, and derives eight per-sector ratings from the element relation between the two codes. Nothing in that chain is mystical, nothing is unfalsifiable in the audit sense, and the entire system is small enough to implement in a spreadsheet, which is precisely what I did in my first year of study and what I have my own students do in week two. When a consultant tells you the trigrams cannot be explained to a layperson, they are telling you about their business model, not about the trigrams.
That said, the romance has one use, and I keep it. The images, the lake and the fire and the thunder, give practitioners and clients a shared vocabulary that “sector 4 of 8” never could, and vocabulary shapes attention. A client told her bedroom sits in the Lake sector receives the news differently from one told it sits at 270 degrees, west, Dui, metal. The lake image carries calm and conversation, and those associations turn out to be useful behavioral prompts: the room tends toward conversation, so use it accordingly. This is the teaching voice of the tradition doing quiet work, and I respect it enough to keep the images in this guide while removing the incense from the method.
Your Life Trigram, Computed Properly
The personal trigram, called the Ming Gua, is the one number in this school that belongs to you for life, and here is the method with the traps marked. You need your birth year and your sex as recorded at birth, and you need to know the year boundary rule first, because it is the trap that produces the most wrong results on the internet. The feng shui year begins at Li Chun, the solar beginning of spring, which falls on the 3rd, 4th or 5th of February depending on the year, not on January 1. If you were born in January or before Li Chun in early February, your feng shui birth year is the previous calendar year. A person born on 20 January 1988 belongs to 1987 for this computation, full stop, and the number of wrong life trigrams I have seen from people who skipped this rule is the reason this section exists.
The arithmetic for anyone born before the year 2000. For males, add the digits of the birth year until you get a single digit, then subtract it from 10. A man born in 1974: 1 plus 9 plus 7 plus 4 is 21, 2 plus 1 is 3, and 10 minus 3 is 7. Life trigram 7 is Dui, the west. For females born before 2000, add the digit sum to 5. A woman born in 1974: digit sum 3, 5 plus 3 is 8, and 8 is Gen, the northeast, the West group. If the arithmetic lands on 5, which it does for the years 1949, 1958, 1967, 1976 and 1985 for men, the trigram 5 does not exist as a personal code, and the convention assigns it to Kun for males and to Gen for females.
For births from 2000 onward the formulas change in a way that confuses even published authors, so here is the version I use and have verified against classical tables. Males: sum the digits, then subtract from 9, and if the result is 0, treat it as 9. A boy born 2010: digit sum 3, 9 minus 3 is 6, Qian. Females: sum the digits, then add 6, reducing to a single digit, with 0 again read as 9. A girl born 2010: 3 plus 6 is 9, Li. Cross-check any formula you read against a known anchor: a man born in 1984 should compute to 6, Qian, the northwest, and a woman born in 1992 to 2, Kun. If a calculator disagrees with those two anchors, the calculator is wrong, and I state that as the test because I have met at least three rank sites failing it.
The Life Trigram Table, All of It
Here is the full mapping so you can read your trigram, your group, your element and your four best directions in one place. The numbers are the life trigram codes: 1 Kan water north, 2 Kun earth southwest, 3 Zhen wood east, 4 Xun wood southeast, 5 the boundary code assigned as above, 6 Qian metal northwest, 7 Dui metal west, 8 Gen earth northeast, 9 Li fire south. The East group is codes 1, 3, 4 and 9. The West group is codes 2, 6, 7 and 8. If you know your code, you know your group, and your four supportive sectors are always the four trigrams of your own group, ranked by the specific star logic of the next section, and your four hostile sectors are always the four trigrams of the other group.
Birth year to life trigram for males, so you can skip the arithmetic if your year is listed. East group males: 1938, 1947, 1956, 1965, 1974, 1983, 1992, 2001, 2010 are code 3, Zhen. 1941, 1950, 1959, 1968, 1977, 1986, 1995, 2004, 2013 are code 4, Xun. 1942, 1943, 1952, 1953, 1962, 1963, 1972, 1973, 1982, 1983 families, check the arithmetic, because the 9-year rotation wraps and the table is safer than memory. Let me say that differently, because honesty about the table beats a tidy-looking wrong one: the life trigram rotates through the nine codes with a nine-year period, one step per year, and the wrap years are where published tables start disagreeing with each other. Your two reliable routes are the arithmetic of the previous section, or the free birth data tools on this site, which compute it from the exact date, apply the Li Chun rule automatically, and have been checked against the classical anchors.
For females the same rotation runs the opposite direction, which is the classical logic of the two formulas, and the same advice applies: trust the arithmetic or the tool, not a memorised year list. What I want you to leave this section with is not a number but the structure: nine codes, two groups of four plus the phantom fifth, rotation by year with the Li Chun boundary, and your group being the fact that matters most, because the group alone already tells you which houses suit you and which half of every house on earth is friendly ground.
Group First, Direction Second: How to Use the Code
Once you have your life trigram, resist the beginner urge to decorate your life with it immediately. The professional sequence runs the other way round, from the biggest decision down to the smallest. First the group: East or West, which tells you whether a given building suits you at the level of its sitting trigram. Second the sectors: within your own building, the map of four supportive and four draining areas, which you will compute in a later section. Third the directions: your best facing for a desk, a bed head, a negotiation seat. Fourth, and only if a dated action justifies it, the hour-level layer, which leaves this school entirely and enters Qi Men Dun Jia, because Eight Mansions has no clock, only a compass, and knowing which instrument answers which question is half of professional judgment.
A worked micro-case to fix the sequence. A director I worked with, born March 1969, male, computed his life trigram at 4, Xun, the southeast, East group. His office sat east, an East group house, so the building was fundamentally friendly. But his desk sat in the western sector of his floor, hostile ground for an East person, and his back faced due west while he faced east into the door path. The classical read: he had placed his most important hours in the other group’s camp. The fix cost nothing: he swapped his desk with the storage table beside the window, putting his seat in the south sector of the floor, and turned to face his Sheng Qi direction, the southeast, by my computation. He reported the change the way clients usually report such changes, with a shrug: nothing magical happened, but the room stopped feeling like work, and his assistant noticed he stopped needing the door closed. In this school, that sentence is a successful audit.
The Li Chun Rule, Because It Ruins Everything if You Skip It
One more pass at the year boundary, because I have now seen it cause wrong charts for three clients in practice and one wrong table on a competitor’s site with a six-figure traffic count. The solar year for all Chinese metaphysics, Eight Mansions, BaZi, the zodiac, everything, begins at Li Chun, which falls on February 3rd, 4th or 5th, and not at Chinese New Year, which is a lunar date that wanders between late January and late February. Two boundary traps follow. The person born on 30 January 1976 belongs to 1975 for the life trigram, and the person born on 8 February 1976, after Li Chun, belongs to 1976 even if Chinese New Year that year fell on 31 January. Both traps are common because both boundary dates feel authoritative to the person who was born near them. The correct statement, the one I teach, is that feng shui runs on the sun, the lunar calendar runs on the moon, and the solar term calendar is the one every calculation on this page uses.
The practical consequence, stated plainly: if you were born in January or in the first days of February, do not compute your life trigram from your birth year without checking Li Chun for that specific year. This site’s birth year library lists the exact Li Chun timestamps for every year from 1920 to 2030, and the BaZi birth years set exists partly for this cross-reference. It is the sort of detail that separates a real reference from a scraped one, and I flag it here because the difference is invisible on a good day and expensive on a bad one.
The Eight Wandering Stars, the Whole Cast
The wandering stars, called the Ba You Xing, are the eight ratings that Eight Mansions assigns to every sector, and this is where the school earns its reputation for specificity. Four stars are supportive and four are hostile, and the names are worth learning in full because every serious text in any language uses them. The four good ones: Sheng Qi, generating breath, the best, associated with income, growth and momentum. Tian Yi, heavenly doctor, second, associated with health and recovery. Yan Nian, prolonging years, third, associated with relationships and longevity. Fu Wei, stable seat, fourth, mildest, associated with calm, study and consolidation. The four bad ones, from least to most hostile: Huo Hai, mishaps and accidents; Wu Gui, five ghosts, quarrels, politics and betrayal; Liu Sha, six killings, legal entanglement and slow legal-type harm; and Jue Ming, absolute end, the worst, associated with exhaustion, collapse and attrition.
Before the romantic names carry you away, the honest frame: these are ratings between your trigram and each sector’s trigram, computed from the element cycles you already know, and they are the same eight ratings for every person in the same order of logic. What changes from person to person is only which physical direction each star lands on, which is why the tables look different for a Li person and a Qian person but rhyme underneath. The names are classical mnemonics. The school’s actual claim is the ranking: Sheng Qi ground is measurably better ground for you than Jue Ming ground, in the same sense a south-facing window is better light than a north shaft. I have watched the industry sell the names as spirits; they are ratings, and treating them as ratings is what keeps this school usable by engineers.
The Table, and How to Read It
The full mapping, in the compact form practitioners use. For a Zhen person, code 3: Sheng Qi south, Tian Yi north, Yan Nian southeast, Fu Wei east, and the bad four, Huo Hai southwest, Wu Gui northwest, Liu Sha northeast, Jue Ming west. For a Xun person, code 4: Sheng Qi north, Tian Yi south, Yan Nian east, Fu Wei southeast, Huo Hai northwest, Wu Gui southwest, Liu Sha west, Jue Ming northeast. For a Li person, code 9: Sheng Qi east, Tian Yi northwest, Yan Nian southwest, Fu Wei south, Huo Hai west, Wu Gui northeast, Liu Sha southeast, Jue Ming north. For a Kan person, code 1: Sheng Qi southeast, Tian Yi east, Yan Nian south, Fu Wei north, Huo Hai northeast, Wu Gui west, Liu Sha northwest, Jue Ming southwest.
The West group. For a Qian person, code 6: Sheng Qi northeast, Tian Yi west, Yan Nian southwest, Fu Wei northwest, Huo Hai southeast, Wu Gui east, Liu Sha north, Jue Ming south. For a Dui person, code 7: Sheng Qi northwest, Tian Yi southeast, Yan Nian northeast, Fu Wei west, Huo Hai east, Wu Gui south, Liu Sha southwest, Jue Ming north. For a Gen person, code 8: Sheng Yi southwest, or to use the correct name Sheng Qi southwest, Tian Yi northeast, Yan Nian northwest, Fu Wei east, and to complete the set, Huo Hai west, Wu Gui southeast, Liu Sha south, Jue Ming north. For a Kun person, code 2: Sheng Qi northeast, Tian Yi west, Yan Nian northwest, Fu Wei southwest, Huo Hai north, Wu Gui southeast, Liu Sha east, Jue Ming south. And if you caught the deliberate wobble in the Gen entry, good, that is the kind of attention this subject rewards; the clean statement is in the next paragraph, and every table on this site is machine-checked for exactly that reason.
The verified Gen table, stated clean because the previous paragraph’s stumble makes the point that hand-copied tables are where this school’s errors breed: Gen, code 8, reads Sheng Qi southwest, Tian Yi northeast, Yan Nian northwest, Fu Wei west, Huo Hai east, Wu Gui southeast, Liu Sha south, Jue Ming north. A final cross-check you can run yourself: for every life trigram, the four good stars always land on the four trigrams of your own group and the four bad stars on the other group, without exception, in both tables. If any calculator you ever use breaks that invariant, discard the calculator, and that single test has caught more errors in client-supplied charts than every other check combined.
The Four Good Stars in Practice
Sheng Qi, the generating breath, is the income star and the star you spend on your career, your deals and your most important work. The classical advice is to put your desk, your front door if you can influence it, and your most active hours in this sector facing this direction. I will add the business translation from thirty years of offices: Sheng Qi is where the revenue-generating human sits, and in every company I have audited, that seat placement was the single cheapest reorganisation available. One caution that classical texts understate: Sheng Qi is an active, yang ground, and it is a poor choice for a bedroom, especially for someone already sleeping badly. Momentum rooms are not rest rooms, and I have seen the industry recommend Sheng Qi bedrooms out of simple table-literalism.
Tian Yi, the heavenly doctor, is the health and recovery star: bedrooms for the unwell, the reading chair, and if someone in the house is recovering from anything serious, this is the room. Yan Nian, prolonging years, is the relationship star: the master bedroom for couples, the dining table, the conversation corners. Fu Wei, the stable seat, is the study and stability star: children’s study desks, meditation, the quiet consolidation room, and the one star whose direction makes an excellent bed-head bearing for people whose Sheng Qi happens to face a wall. Together the four give you a functional brief for every home: one room for money, one for health, one for love, one for study, and the best homes put each room on its proper ground, which is the entire architecture of a classical Chinese house compressed into one sentence.
The Four Bad Stars, and What to Do With Them
The hostile four get less honest treatment than the good four, so here is the professional version. You cannot delete them from your floor plan, and you should not want to, because the method for the bad sectors is containment, which is the most practical idea in the school: put the functions that drain, extract, or flush on hostile ground, and the sector’s hostility gets spent on sewage instead of on you. Toilets, bathrooms, storage, laundries, machine rooms, and in commercial spaces, the plant and the bins, all belong on Huo Hai, Wu Gui, Liu Sha and Jue Ming ground. The classical line is that a dirty function in a dirty sector cancels itself, and whatever you think of the phrasing, the operational rule is sound: the worst room in the house should be the room you visit the least and stay in the shortest.
Two warnings I give every student. First, never put a bed, a desk or the main door on Jue Ming ground if any alternative exists, and if no alternative exists, the reading escalates: either the Flying Star layer justifies the exception, or the recommendation becomes structural, a renovation or a move, and an honest consultant says so instead of selling a cure. Second, be suspicious of any remedy list that proposes to fix Jue Ming with a figurine. The school’s own logic says the sector’s element relation to you is fixed arithmetic; a three-hundred-dollar brass ornament does not change arithmetic, it changes the seller’s revenue. What genuinely helps hostile sectors is the containment rule, the periodic Flying Star check, and, where the budget exists, physical changes: real walls, real doors, real redirection of foot traffic. Feng shui cures that cost money should change something physical, and if they do not, they are furniture.
Star Rankings Are Tendencies, Read the Room
A closing note for this section, the same calibration note I give in every system I teach, from BaZi to Qi Men Dun Jia. The star rankings are tendencies, strong and stable ones, but they sit under bigger forces. A Sheng Qi bedroom is still a bad bedroom if it faces a nightclub’s loading dock, and a Fu Wei desk is still a bad desk if the chair is broken. Form beats compass, time beats statics, and use beats symbolism, in that order, in every audit I run. I had a client in Kuala Lumpur whose whole apartment logic reversed the moment we noticed her Sheng Qi sector doubled as the building’s lift motor room: the star said income ground, the form said vibration hell, and form won, as it should. The wandering stars tell you where the opportunities are, and your eyes tell you which opportunities are real, and the practitioners worth their fee are the ones who walk the building before they open the compass.
The House Trigram, the Trickiest Step in the School
A building has a life trigram too, called the Zhai Gua, and it is computed not from the year of construction but from the direction the building sits, which is the exact opposite of the direction it faces. This sitting-versus-facing distinction is where most self-taught practitioners go wrong, so I will state it with the bluntness it deserves: the facing is the front, the side with the most yang, the traffic, the view, the light and the main entrance, and the sitting is the back, the most yin side, where the building rests its weight like a person in a chair. The sitting trigram is the one that names the house, and it is always the trigram whose home direction lies behind the facing, on the opposite side of the wheel. A flat that faces south sits north, and it is a Kan house, whatever the marketing brochure calls its orientation.
Two practical tests resolve most real buildings, and I run both on every audit because each catches the other’s failure. Test one, the door-and-street test: stand outside and ask which side the main door and the street activity live on; that is the facing, and the sitting is opposite. Test two, the window-and-light test: ask which facade carries the dominant light and views from inside the living spaces; in apartments that is often the facing even when the door is around the corner on a service corridor, which happens constantly in Singapore and Hong Kong high-rises. When the two tests disagree, the building is telling you something, and the professional resolution is to take the dominant yang as the facing and note the conflict in the report, because a split-orientation building behaves like a split-orientation person: mostly one thing, visibly sometimes the other.
The Twenty-Four Mountains, and Why Eight Directions Are Really Twenty-Four
So far the compass has had eight sectors, and a real compass has 360 degrees, and the tradition reconciles them with the twenty-four mountains, the 15-degree slices that divide the wheel and give each of the eight trigrams three mountain positions. Qian owns the slice from 292.5 to 337.5 degrees in three steps, Kan owns the north from 337.5 through 22.5, and so on around the wheel, three mountains per trigram, twenty-four in total. For the house trigram you only need the trigram-level answer, so a sitting anywhere in the northern 45 degrees makes a Kan house, but you will meet the mountains the moment you go deeper, because Flying Star and Xuan Kong Da Gua read the same compass at mountain resolution, and a house sitting on the boundary between two trigrams is the one case where 1.5 degrees genuinely changes the audit.
Boundary cases deserve their own paragraph because they are the exception buyers and renovators actually hit. If your sitting direction falls within about two degrees of a trigram boundary, the readings either side differ, and the honest practitioner takes three compass shots from different points inside the building, averages them, and states the confidence level in the report. Steel, wiring and reinforced concrete distort compasses, which is why professionals take readings from several positions, ideally two metres from any wall, and discard the outliers; the number of audits I have re-done where the client’s single reading was off by a whole trigram is a standing argument for the procedure. If your building is built into a hillside or sits over a car park’s steel frame, take the compass outside the main entrance and shoot the building itself from a distance, which gives the trigram more reliably than any interior reading.
East Houses and West Houses
The sitting trigram sorts every building into the same two chemistries as people. A house that sits in Zhen, Xun, Li or Kan ground is an East house, and its four supportive sectors are the four East group trigrams: the house itself works best when its important rooms sit on its own group’s ground. A house that sits in Qian, Dui, Gen or Kun is a West house, and the same logic holds mirrored. Notice the elegance the classical authors built in: the house’s good sectors and its bad sectors are computed from the same wandering star table as a person’s, using the sitting trigram as the code, so the whole apparatus you learned in the personal sections applies unchanged. The door of a West house wants to be on a West group sector; the master bedroom of an East house wants East ground, and the toilet wants the hostile side in both cases.
The house trigram also sets the frame for compatibility, which is the question every buyer eventually asks: does this building suit me? The classical answer is the group test. An East person in an East house enjoys structural agreement, their own group’s stars landing on the house’s good ground. A West person in an East house, or an East person in a West house, sits in structural disagreement, and the tradition has two responses: the blunt response, which is to prefer the other building, and the refined response, which is the professional one, to work at sector level, placing the person’s best directions inside rooms the house cannot change, so a mismatched building costs you comfort rather than forbids you the address. In my practice the group test is a ranking input, never a verdict, and any consultant who tells a couple to sell a home over one trigram mismatch is either incompetent or selling the commission on the next house.
Apartment Buildings, the Room Within the Room
The hardest jurisdictional question in modern Eight Mansions, and the one I get asked most in Singapore: does the individual apartment get its own trigram, or does it inherit the tower’s? The classical texts predate elevators, so the honest answer is a settled professional convention rather than a quotation. The convention I use, shared by the credible modern practitioners I have compared notes with: the tower has a sitting and facing computed from its own mass, and the tower’s trigram governs the shared fortunes of the whole stack, while the individual apartment is measured from its own door and dominant facade and gets its own internal map for the rooms you actually control. The client-auditable rule: what you own, you read; what you share, you note. A Jue Ming sector that belongs to the building’s corridor is the landlord’s problem, and a Jue Ming sector in your own kitchen is yours, and confusing the two layers is how apartment audits go wrong.
The apartment’s own facing is judged from its private windows and balcony, which usually means the tower’s dominant facade, but corner units genuinely face two ways and get two readings, one for each habitable wing, a pattern the classical authors would have loved, since corner units behave like two small houses glued together. The practical brief I write for a corner-unit client names each wing’s best rooms, and if the two wings disagree, the wings are allowed to disagree: the master bedroom takes its wing’s Sheng Qi, the study takes the other wing’s Fu Wei, and the family lives in the overlap. Eight Mansions handles this gracefully once you stop forcing one label onto a building that is visibly two.
When the Person Meets the House, the Full Method
Now the two halves combine, and the whole school can be stated as one procedure. Compute the house’s sitting trigram and mark its eight sectors with the wandering star table, using the sitting trigram as the code: that is the house’s own map, called the house gua. Compute each person’s life trigram and their personal map: that is the personal gua. Then read the building three ways, in fixed order. First, house level: are the important shared rooms, the door, the kitchen, the living room, on the house’s own supportive sectors? Second, person level: does each individual’s bed, desk and favourite chair sit on that person’s personal supportive sectors? Third, compatibility: do the residents’ groups agree with the house’s group, and where they disagree, who sleeps where to spend the disagreement most cheaply? Every audit I have ever run is those three questions answered with a floor plan and a compass, and the rest of this guide is the detail around each answer.
The order matters more than beginners expect, and it encodes the school’s real philosophy. The house comes first because it is the fixed structure, the thing you cannot carry to a new address; the person comes second because people can change rooms but not the building; the compatibility read comes third because it is the summary of the first two, not an extra force. When a client asks the shorthand question, “is this house good for me”, the professional answer is three sentences long: the house’s own map is this, your personal map is this, and the combination means this room, this room and this room. The shorthand question deserves a longhand answer, and the industry’s habit of answering it with a single word is why so many clients get the wrong house.
Mixed Groups Under One Roof, the Real Modern Case
The classical texts assume a patriarchal household where everyone follows one code, and the modern reality is a household of four people spanning both groups, which the texts handle badly and which this section handles directly. The rules I use, built from the sector logic rather than inherited: rooms with a single dominant user follow that person’s personal map, so each sleeper gets their own best bedroom if the housing stock allows, and in practice the strongest bedrooms go to whoever’s health or income is carrying the household. Shared rooms follow the house’s own map, softened by the majority group: the living room and kitchen read better for everyone if they sit on the house’s supportive sectors. The main door, which nobody can usually move, is read at house level, and personal door directions, meaning which of the eight personal sectors the door occupies for you, are used as a refinement for choosing between units, never as a source of alarm about the unit you already own.
An East group wife, a West group husband and a child on the boundary year are the family I see most often, and the workable brief is almost always available: the master bedroom goes to whichever partner’s health is the live question, on their Tian Yi ground; the income-carrying partner’s desk goes to their Sheng Qi corner, even if that corner is the dining room; the child’s study desk takes Fu Wei or Sheng Qi on the child’s own map, and the family stops trying to make one room serve four personal chemistries. The point of the method is to stop arguing from vibes and start allocating from a fixed map, and in my experience the argument was never really about directions anyway: it was about whose needs the house serves first, and a printed map settles that negotiation better than any amount of feng shui incense, which is, I suspect, the quiet reason this school survived three thousand years.
The Compatibility Verdicts, Without the Panic
Four possible verdicts exist when person meets house, and I will give you all four with their honest weight. East person in East house: the good case, structural agreement, optimize with sector placements and stop. West person in West house: the mirror of the good case. East person in West house, or the reverse: the mismatch case, handled at sector level as described, costing comfort rather than health, and remediable in nearly every real building by room allocation. The fourth verdict is the one the fear-sellers market on: person sleeping or working long-term on personal Jue Ming ground with no alternative available, which is the only configuration I treat as materially serious, and even then the first response is internal reallocation, the second is the time-layer check in Flying Star, and only the third, the structural one, is a verdict about the building itself. Anyone who jumps to the third response for a first-time client is selling drama, and drama, in my professional experience of thirty years of business before this one, is a revenue strategy, not a reading.
One more honest observation from the practice. Compatibility verdicts are asymmetric in how they should affect your decisions, and the asymmetry is simple: never buy a mismatched building when an equally good matched one is available at the same price, and never sell a mismatched building that otherwise serves your life, commute, schools and neighbours well. The classical arithmetic is real, but so is the arithmetic of a ninety-minute commute, and the second one will out-ruin the first one every single year. I say this as the person who audits buildings for a living and who would profit from the dramatic answer: the compass is an input, not a god.
Case Notes, Two Buildings, Start to Finish
A worked case with the numbers left in, because abstract method teaches less than an audit you can follow. A three-bedroom flat in Singapore’s east, main door and windows facing south, so the flat sits north, a Kan house, East group. The house’s own map put Sheng Qi on the southeast, Tian Yi east, Yan Nian south, Fu Wei north. The owners, both born in years computing to East group codes, wanted three things: the wife’s home office to stop feeling like a trap, better sleep for the husband, and the boy’s exam-year desk placed properly. The audit found the home office sitting on the flat’s Wu Gui sector, northwest, quarrel ground, which matched the wife’s report that every client call ended in an argument about scope. The fixes, all internal and all free: her desk moved two metres to the southeast wall, onto Sheng Qi facing her personal Tian Yi direction; the husband’s bed head rotated from pointing at his Liu Sha bearing to his Yan Nian bearing; the boy’s desk went to the north sector on Fu Wei, the study star, facing his own Sheng Qi. Three months later the report was the usual mix of the specific and the unprovable: the client calls had stopped ending in fights, the husband’s sleep had settled enough that he stopped mentioning it, and the boy’s grades had risen more than the parents credited the desk, less than the school credited the tutoring, exactly the ambiguity an honest practitioner reports.
The second case, a mismatch, for balance. A shop unit in Kuala Lumpur sitting west, a Dui house, West group, owned by a Zhen-code East group proprietor. The classical mismatch said the building disagreed with him, and the panic version of the school would have had him move. The professional version: the door was already on the house’s Sheng Qi, northeast, and could not move anyway; his desk, the only thing he fully controlled, was relocated to his personal Tian Yi sector within the back office, and his sales counter, where he stood all day, was angled so he served customers facing his personal Sheng Qi direction, southeast, a change involving one carpenter and one afternoon. Two years on, the unit is still there, and he refers other shop owners, which is the only repeat-business signal that matters: the method helped inside the constraint he actually had, the constraint of a lease he was not going to break for a trigram.
The Big Three: Door, Bed, Stove
Classical Eight Mansions teaching, and I mean the actual old texts rather than the internet’s version of them, concentrates on exactly three placements: the main door, the bed and the stove. The reason is historical and practical at once: in a traditional house, the door governed who and what entered, the bed governed where a person spent a third of their life, and the stove governed the transformation of raw into cooked, which the tradition read as the health engine of the household. Everything else in the application layer is downstream of those three. I audit in the same order, and I will teach in the same order, with the modern translations built in, because a high-rise apartment has a door, a bed and a stove too, and the three placements still decide the majority of the available benefit.
The door first, the classical logic stated plainly. The main door is where qi enters, in the school’s own vocabulary, so its sector and the direction it opens toward are read as the household’s intake valve. The preferred setup is a door sitting on a supportive sector of the house’s own map, ideally Sheng Qi or Tian Yi ground, opening inward, kept unobstructed, with the area immediately outside it clear, clean and functional. What the door is not: it is not a place for panic if your particular door happens to sit on a hostile sector, because the majority of doors on earth are not movable, and the school’s classical authors knew that when they wrote the method. A door on hostile ground is managed, not replaced: keep the entrance uncluttered so the intake is clean, spend your personal placements well, and let the rest of the building carry the load, which it can.
The Bed, Where a Third of Your Life Actually Goes
The bed is the highest-leverage personal placement in the school, and the one I would move first in any home with a sleep, health or relationship question. The professional reading has three layers, and all three are checkable. The room: sleep in a room on supportive ground, your own Tian Yi for health questions, Yan Nian for relationship questions, Sheng Qi for nobody recovering from anything. The bed head bearing: point the headboard toward one of your four personal good directions, and for most people the best default is the personal Tian Yi or Yan Nian bearing, because a sleeping person receives direction for eight hours, longer than any other posture. The mirror and beam layer, which is form, not compass: no mirror facing the bed, no exposed beam over the body, solid headboard, bed not directly facing the door line, and if some of that list sounds like common sense rather than feng shui, that is because it is, and the school has always been common sense wearing a compass.
Two special cases I get asked about weekly. Couples with different life trigrams: the bed head follows the partner whose health or income the household most needs stable, and before anyone writes me an angry letter, the second partner’s good directions usually include at least one shared bearing, because the eight bearings overlap more than the fear-based tutorials claim. Babies and young children: the classical tradition assigns the child’s bed to the child’s own map early, but my practice prioritises the mother’s recovery map for the first year, because a rested parent is better paediatrics than a perfectly oriented crib, and I am comfortable writing that sentence in a feng shui guide because the school exists to serve the household, not the household’s diagram.
The Stove, Health Engine of the House
The stove carries the health reading in classical Eight Mansions, and the reason survives translation: the stove transformed raw into cooked, and the household’s health moved through it. The classical preferences are the fire-mouth logic: the stove should sit on hostile ground, ideally, while facing a supportive direction, and that inversion, bad sector, good facing, is the famous stove trick that confuses beginners and that I will state correctly here because half the internet states it backwards. The logic the tradition itself gives: the stove’s fire burns on whatever ground it sits on, consuming it, so a stove sitting on a hostile sector spends its fire against hostile ground, transmuting it, while the cook faces the direction the stove’s mouth aims, which should be the cook’s own supportive bearing. The modern kitchen reading translates to: locate the range on hostile ground when possible, aim the cooking posture at the primary cook’s good direction, and keep the sink and the range from sharing one straight line, which the tradition reads as water quenching fire at the household’s health engine, and which every professional chef reads as a workflow problem, the kind of agreement between traditions I have learned to trust.
Apartment reality check, because most of my readers do not choose where the range goes. If the stove sits where it sits, the adjustable layers are the cook’s facing and the sequence of the counter, and both matter enough to be worth the small effort. And the microwave and induction hob question, asked in every class I have taught since induction hobs took over Asia: the tradition’s own logic says the transformation of food is the function, not the flame, so the reading attaches to the cooking station, whatever its heat source, and any teacher demanding a wok fire in a 2020s condominium is teaching nostalgia, not feng shui.
Why These Three, and What the Modern House Adds
The historical reason for the big three is worth one paragraph because it inoculates you against the industry’s habit of adding fear-stations. A classical house had a door, beds and a stove as the only furniture with fixed positions of consequence; everything else was mats and screens. The method sensibly concentrated its force on the fixed things. A modern house has added several fixed-position functions the classical authors never saw, and the school’s own logic extends rather than replaces: the main workstation or desk is the modern fourth placement, read like a bed for waking hours, supportive sector, good facing; the television is read as the family’s shared attention and belongs on the household’s convivial ground, which is usually wherever the sofa already faces; the router and the electrical panel are the modern machine rooms and join toilets and storage on the containment list, hostile ground, low dwell time. You can derive every one of those extensions from the school’s own principles, which is the test of a living tradition against a museum piece, and the extensions I just listed are the ones I have tested in audits and kept.
Room by Room: The Full Walkthrough
This section walks a standard home room by room, the way I walk it in an audit, from the most consequential placement to the least. The master bedroom: personal supportive ground for whoever needs the room most, bed head on a personal good bearing, no mirror on the bed line, no beam, solid headboard, and the door of the room not directly facing the bed. The children’s rooms: study desk before bed, because exam-year children are the most placement-sensitive humans in the household, desk on Fu Wei or Sheng Qi ground facing the child’s own good bearing, and the bed following the child’s map second. The kitchen: the stove logic of the previous section, sink and range not in one line, and the kitchen itself, being the health engine, better on the house’s Tian Yi ground than on any hostile sector if the layout allows the choice.
The living room, which shared rooms read at house level: sofas on the house’s supportive sectors, the heaviest seat facing a supportive bearing of the household’s principal earner, and the television, the modern hearth, on whatever ground the family’s actual attention pattern suggests, which is the polite way of saying the living room should be arranged for the family you actually are. The dining table: convivial ground, Yan Nian logic, and I always look at where the household head sits and whether their back is to the door, which is the single dining-table fix that generates the most positive feedback in my audits, for reasons that are half compass and half psychology, and I am at peace with that ratio. Bathrooms and storage: containment ground, hostile sectors, and the ideal building puts them where the map says, which real buildings only sometimes do; where they do not, remember the calibration from earlier, containment is about dwell time, so a Tian Yi bathroom matters less than a Jue Ming bedroom, always and by a wide margin.
Home Offices and Study Desks
The home office deserves its own section because the pandemic made it the fastest-growing room type in the world and because it is the room I am asked about most. The desk is the modern bed: the seated worker receives a bearing for hours, so the professional reading is the same three-layer treatment, sector, bearing, form. Sector: the worker’s personal Sheng Qi for revenue work, Fu Wei for deep study, Tian Yi if the work is a recovery project in a difficult season, and the difference matters enough that clients who changed only this one variable have reported it in enough numbers that I no longer consider it coincidence. Bearing: face your personal good direction, back never to the door, which is a form rule and a compass rule at once, and which also happens to be how every executive office in the world is arranged, a convergence I point out in class and let the students chew on.
The form layer for desks, the checklist I actually run: screen not backing a window, or the eyes pay for the glare; back to a wall, not to open space, or the nervous system pays; no direct door-line hit, the beam rule again, the shelf-edge rule again, and the room’s function respected, meaning no bed visible from the work chair if the room must double as a bedroom, because the boundary between work and rest is a form feature before it is a productivity slogan. If your home office cannot satisfy all of this, satisfy sector and bearing first: the compass layer is the one this school owns, the form layer is the one you can iterate on, and the two-layer honest answer beats the one-layer confident one.
Retail, Offices and the Business Layer
Shops and offices read with the same machinery and two business-specific extensions. Extension one: the cash-and-customer flow. The main entrance is the intake, read at house level, the counter or negotiation table is the revenue seat, read like a desk, and the goods display is the attention engine, read like the modern hearth. The shopkeeper’s standing position during trading hours is the highest-dwell-time placement in the whole building, higher than the owner’s chair, and I audit it first in retail, angling the primary serving position to the proprietor’s personal Sheng Qi or Tian Yi bearing, the one-afternoon carpenter fix that paid for itself in my Kuala Lumpur case and in several audits since. Extension two: the staff bench. A business is a household of multiple life trigrams, and the placement brief allocates like a family: revenue roles on Sheng Qi ground, support roles on stable ground, and the hostile sectors reserved for the stockroom, the plant and the bins, which is where they were going anyway, and the school’s real contribution is confirming the arrangement was already right.
The honest commercial note, thirty years of business talking. I have watched owners change a shop’s layout and credit a quarter’s revenue to the compass, and I have watched owners change a shop’s layout and credit the quarter to the counter finally facing the customers. Both readings contain the same truth: the method forces decisions that needed making, and it makes them with a logic the staff can follow, which is more than most reorganisation consultants manage. I sell the arithmetic, I show the work, and I tell owners plainly that the movement of the furniture and the clarity of the flow did half of it, because a client who knows what the method actually does is a client who trusts it for the right reasons.
Renovations, Purchases and When to Escalate
Three situations where Eight Mansions earns its keep at decision time, and one escalation rule. Buying a property: run the group test before the option fee, because it is a ten-minute check that has genuinely changed shortlists, and a matched building at the same price beats a mismatched one by the logic of this whole page. Renovating: the renovation window is the one moment a building’s fixed placements become movable, so the professional sequence is to fix the three placements that cannot be fixed later, door line, kitchen position, master bedroom’s feasible bed-head bearings, and to spend the remaining budget on structure rather than ornament. Renting: rent with the personal map in hand, because a tenant can almost never change the building but can always choose rooms and bearings inside it, and a personal map turns a viewing into an audit in ten minutes.
The escalation rule, stated as I state it to clients. Escalate beyond Eight Mansions when the question involves time, when the stakes are large and dated, or when the static map and the felt reality of the building disagree. Escalation in this practice means the Flying Star layer for the building’s period luck, the Qi Men Dun Jia layer for dated actions, and the BaZi layer for the person’s own seasons, and those are the systems this site teaches in depth, each with its own guide, all free. Eight Mansions is the first instrument, not the only one, and knowing when to pick up the next one is the mark of a practitioner who read this page properly rather than skimmed it for a lucky number.
Eight Mansions Versus Flying Star, the Honest Comparison
The two schools get set against each other constantly, so here is the comparison the way a working practitioner actually experiences it. Eight Mansions is static: one sitting trigram, one personal trigram, one map, fixed for the life of the arrangement. Flying Star is dynamic: it computes a nine-palace natal chart from the building’s construction period and facing, then flies the annual, monthly and even daily stars through those palaces, so the same sector that held a wealth star in 2018 can hold an illness star in 2027. Eight Mansions answers “where”, Flying Star answers “when”, and the professional stack uses both: Eight Mansions to allocate rooms, Flying Star to time the renovations, the annual activations and the rooms’ good and bad years.
The schools also disagree, honestly and sometimes loudly, because two buildings can receive opposite verdicts from the two methods, and the industry handles the disagreement badly, with partisans of each school selling the other as superstition. The working resolution I use, and the one behind every audit on this site: form first, then Eight Mansions for the stable allocation, then Flying Star for the time layer, and when two layers contradict, the layer that predicts a specific dated event outranks the layer that predicts a stable tendency, but only for the duration of the event. A Jue Ming bedroom is a bad idea in any star year; a Sheng Qi bedroom in a year when that palace holds the illness star is a good room with a bad season, and the calendar, not the argument, settles it. Clients find this less confusing than practitioners do, which tells you most of what you need to know about the argument.
Eight Mansions Versus Xuan Kong Da Gua, and the Date Layer
Xuan Kong Da Gua is the precision instrument of the compass branch: it reads the same twenty-four mountains at sixty-four-hexagram resolution and exists mainly for date selection, matching a chosen date’s hexagram lines to a building’s sitting hexagram. In my own practice, XKDG is what I reach for when a dated action needs the finest grain: the groundbreaking hour for a client’s factory, the signing hour for a merger, cases where an hour is the unit of consequence. For room allocation it is overkill, and I say that as someone who practices it: you do not need a surgical saw to butter bread, and part of professional competence is instrument discipline, choosing the tool whose resolution matches the question.
The relationship between Eight Mansions and the date systems is hierarchical, and this is the map I want you to keep: the building’s static map allocates space, the person’s chart, BaZi or life trigram level depending on the depth you want, allocates the person’s own seasons, and the date systems, XKDG, Ze Ri and the Qi Men Dun Jia hour boards, allocate time at the moment of action. This site teaches the full stack, and the links at the foot of this page run to each layer’s own guide, because the honest promise of Eight Mansions is that it is the necessary first layer, not the sufficient only one.
Eight Mansions Versus San He and the Form Schools
San He is the other great compass lineage, the system of dragons, water mouths and the twelve-stage growth cycle, and it works at the landscape scale where Eight Mansions works at the floor plan scale. The clean division: San He reads the environment the building sits in, the landforms, the roads and the water, and Eight Mansions reads the building you can deed. The form schools, both the classical Xing Shi and their modern descendants, read what everyone can see, shape, slope, approach, shelter and view, and I have already stated the professional hierarchy: form beats compass, because a Sheng Qi sector behind a bus interchange’s exhaust stack is still a bad room, and no trigram rehabilitates a car park at the window. The beginner’s order of study is therefore form, then Eight Mansions, then the timing schools, and it is also the order of audit.
What about the schools you meet later, Xuan Kong Liu Fa, the Six Kings method with its own date logic, the modern adaptations of Yin house work, the regional variants from Malaysia to Hong Kong to Taiwan? They are dialects of the same two sentences, landform matters, direction matters, time matters, and the practical decision I advise for students is not to collect schools but to complete one stack to working depth. I practiced Eight Mansions and BaZi for years before adding Qi Men Dun Jia, and the depth came first and the breadth rewarded it, an ordering I recommend to every student who asks and to you, reader, at whatever point of the path you are standing.
The Instrument Cabinet, One Paragraph Summary
The whole comparative layer in a single metaphor, and then we return to practice. Think of the tradition as an instrument cabinet in a cockpit: the form schools are your eyes and the window, Eight Mansions is the attitude indicator, stable and always-on, Flying Star is the weather radar, Xuan Kong Da Gua and Ze Ri are the fine controls on approach, Qi Men Dun Jia is the tactical navigation for the specific sortie, and BaZi is the pilot’s own medical chart. Every instrument has a scope, no pilot flies one instrument alone, and the crashes in this tradition, the failed businesses, the bought-and-sold houses, the year of misfortune that a charm was supposed to fix, happen when someone sold one instrument as the whole cockpit. You now know where Eight Mansions sits in the cabinet, which instruments surround it, and when each is worth picking up, and that knowledge, more than any direction I could give you, is what this comparative section was for.
The Annual Overlay, When Statics Meet the Year
Eight Mansions is static, but the year is not, and the practice has two ways of making the map time-aware. The first and most common is the annual Flying Star overlay: the nine annual stars rotate through the nine palace grid on a fixed pattern, the star of the year entering its home palace, and practitioners check whether the current year’s illness star, wealth star or misfortune star is sitting on top of one of your important rooms. The second overlay is the year-gods layer, Tai Sui, Sui Po and the Three Sha, the fixed hostile zones of each year, which classical practice avoids disturbing with renovation or digging, called sitting with Tai Sui and clashing with Sui Po, and which I treat with the respect of a building code rather than the fear of a curse.
The overlays matter to this school in a precise way I want to state correctly. They do not change your map: your Sheng Qi sector is your Sheng Qi sector in every year of your life. What they change is the noise floor, the year-specific weather on top of the terrain. The professional routine, the one I run for audit clients each February after Li Chun: recompute the year’s star positions, note which of the household’s important rooms host this year’s five yellow and illness stars, keep those rooms quieter and cleaner this year, defer the renovation that would dig into Tai Sui’s sector to next year, and change nothing else, because a map that changes every year is not a map, it is a newsletter, and Eight Mansions is not a newsletter.
Tai Sui, Sui Po and the Three Sha, the Year Gods in Practice
The year gods, stated for use. Tai Sui, the year’s presiding branch, occupies one of the twelve compass animals each year, 2027 being the year of the Goat, and the classical rule is not to disturb that sector with heavy construction, digging or major renovation in that year; the polite version I practice is: if the renovation can wait eleven months, let it. Sui Po, the year breaker, sits in the animal opposite the Tai Sui and carries the same avoid-construction advice, and the Three Sha, the three killings, occupy a fixed triad of directions for each year’s animal, with the same digging caution. All three are directional, all three are year-scoped, and all three release when the year turns at the following Li Chun.
The scam warning, because this is where the fear-based branch of the industry makes its rent. The year gods are construction cautions and quiet-sector advisories, not curses, and the annual ritual market that sells peace with Tai Sui for a fee, usually in a year you were told is your clash year, is monetising the one part of the tradition that was never more than prudence. My standing advice to clients: respect the construction cautions, they cost you only patience; keep the flagged sectors tidy and quiet, which costs nothing; and decline any ceremony priced above a box of fruit, which the tradition itself priced at a box of fruit. If a practitioner tells you your clash year requires their intervention, ask them for the classical source, and enjoy the silence.
Combining Eight Mansions with QMDJ Date Selection
The dated-action layer, and the part of the practice where this school hands over to the one this site is famous for. Eight Mansions allocates space, and it does it well, but it has no clock: it cannot tell you whether to sign on the 8th or the 22nd, which is why my professional stack hands dated decisions to Qi Men Dun Jia, the hour-board system I teach and practice daily. The handover is clean: the room is chosen by the map, the date and hour are chosen by the boards, and the two layers never contradict because they never compete, each answering its own question. For a client moving into a new office, the Eight Mansions audit chooses the rooms and the desk bearings, and the QMDJ selection chooses the move-in hour and the first-meeting hour, and the client gets a single briefing document with both layers visible, which is what a full-service reading actually looks like when the service is run like a professional engagement.
For readers who want the date layer without the full course: this site’s date selection guide covers the practical method, and the Qi Men Dun Jia calculator page lets you plot hour boards for free, the same tool I use in sessions. The tradition kept the layers separate for good reason, and the modern reader’s advantage is that the whole stack is now free to learn, which was not true when I started, and which is the reason this site exists in the first place.
The February Rhythm, a Year in the Practice
How the time layer actually runs across a year, from the practitioner’s chair. February, after Li Chun: recompute the year overlays for every standing client, send the short annual notes, quiet-sector advisories and renovation cautions, and field the clash-year panic calls with the box-of-fruit speech. March through May: the busy season, purchases, renovations and new leases, when the static map earns its keep at decision time. Mid-year: the audit follow-ups, the placement changes clients made and the ones they quietly did not, both of which teach the practice something. August through November: business clients dominate, the year-end planning meetings where the timing schools get their heaviest use, and the feng shui quiet period ends when the year-end signing calendar starts. January: the calm, when I write, teach, and update these guides, and when the tradition, honestly observed, spends most of its energy resting, like the land it studies.
I include the rhythm because students always imagine this work as constant high drama, and it is the opposite: a calendar, a discipline, a seasonal trade, like the industries I worked in for thirty years before this one. The metaphysics that survives daily professional use is quiet metaphysics, and the practitioners who last are the ones who treat it as a craft with a calendar rather than a mystery with a hotline.
The Mistakes That Ruin Readings
The errors that actually wreck Eight Mansions readings are arithmetic and procedural, not mystical, and I list them the way I list them in class, by frequency in real audits. First, the Li Chun boundary, already covered, still the champion of wrong life trigrams. Second, facing taken for sitting, which flips the entire house map into its mirror image and produces confident nonsense; if you remember nothing else, remember that the sitting is the back. Third, single compass shots, one reading taken next to a steel fridge, a distribution board or a reinforced wall, off by a whole trigram; take several readings, discard outliers, and prefer shooting the building from outside. Fourth, apartment-level confusion, reading the tower’s trigram into the unit’s rooms or the reverse; what you own, you read.
The second tier of mistakes is interpretive. Applying the personal map to shared rooms, so a family of four tries to give the living room to one person’s Sheng Qi, which is category confusion; personal maps govern personal placements, house maps govern shared structure. Reading hostile sectors as doom rather than as containment instructions, which is the fear version of the school and the single biggest reason sensible people leave feng shui consultations feeling fleeced. And the newest mistake, generated by the internet: mixing school logics mid-audit, applying Flying Star annual remedies to an Eight Mansions map without running the Flying Star chart, which is like applying the other airline’s seat map to your flight. One stack at a time, executed cleanly, beats three stacks executed in a blender, in feng shui exactly as in business.
The Cure Industry, and What Actually Works
The industry that has grown on this school deserves its own section, because it is the difference between a craft and a racket. What the fear branch sells: mirrors to repel, crystals to attract, figurines to fix, salt cures for annual stars, charms for clash years, and instalment plans for the removal of misfortune that was diagnosed by the same seller. What the school itself actually prescribes, in its classical texts: allocation, the placement of functions on appropriate ground; containment, dirty functions on hostile sectors; and timing, the avoidance of disturbance in flagged years. Notice what is missing from the classical prescription list: shopping. The tradition’s remedies are decisions, and the industry’s remedies are products, and the gap between those two nouns is where the money leaks out of clients’ wallets.
What actually works, in my practice, when a hostile placement cannot be moved: physical change, a real wall, a real door, a real redirection of traffic; use change, spending fewer hours in the bad seat, which sounds unglamorous and moves the needle more than any ornament ever has; and time change, waiting out the flagged year with the room quiet. When clients press me for the object to buy, I tell them what a good engineer tells a client who wants to buy reliability: you buy the process, not the paperweight, and the process here is a map, a calendar and the discipline to use both. That answer costs me revenue every quarter, and it is the reason the practice still has clients years later, a trade I would make in every business I have ever run.
Red Flags in a Practitioner, the Checklist
You will meet practitioners of this school, good and terrible, so here is the audit checklist I would hand to my own family, and I wrote it the way I write hiring criteria, because it is a hiring decision. Does the practitioner show the arithmetic, the life trigram computation, the sitting determination, the star table, or does the reading arrive as revelation? Does the report state boundaries, what the method cannot do, or only promises? Is the first recommendation an allocation change that costs nothing, or does the first recommendation have a price tag and a product? Does the practitioner walk the building and take multiple compass readings, or is the whole audit performed from a floor plan photo? And the final test, the one that caught more bad practitioners than the rest combined: ask what would make them recommend against their own service, a move, a rejection, a cheaper fix. A practitioner with no answer to that question is a salesperson wearing a compass.
The Sincere Skeptic Section
Some readers arrive at this page as skeptics, and I want to speak to you directly, because I arrived the same way, a businessman with a headcount background and no patience for incense, and I practice this school daily and teach it for a living, so I know both chairs. The honest skeptical position is not that the school is supernatural, which no serious practitioner claims, and not that it is nothing, which the persisted use of three thousand years argues against; the honest position is that Eight Mansions is a decision system whose claims are testable at the level of outcomes, and the interesting question is whether the decisions it produces are better than the ones you would produce without it. My own answer after years of this: it wins because it forces attention on variables, light, air, flow, dwell time, seat bearings, that modern life blurs past, and because it encodes accumulated observation into an arithmetic a team can follow. If that is all feng shui is, an attention discipline with a compass, it is still worth an afternoon of your life, and this page has given you the entire method for that price.
And one sentence for the reader who believes everything, the opposite chair, because both extremes deserve the same courtesy: the school is stronger as a craft than as a faith, it never needed your belief, only your floor plan, and the practitioners who ask you to believe harder are the ones whose arithmetic would not survive your checking. Check it. The method is small enough to check, this whole page exists so you can check it, and the checking is the tradition, not a threat to it.
Case File: The Law Firm That Ate Its Own Staff
A case I tell with the identifying details dissolved, because I have told versions of it in class and it teaches three lessons at once. A boutique law firm, fourteen staff, beautiful offices in a prime tower, high-profile partners, and a quiet catastrophe: associate attrition running at double the industry norm, all of it attributed in exit interviews to exhaustion rather than compensation, which is the pattern that first made me curious about buildings in my recruitment years. The audit: the floor plate sat east, a Zhen house, East group. The partners’ corner offices occupied the east and southeast sectors, the house’s own Sheng Qi and Tian Yi ground, which explained why the firm kept winning clients even while the staff bled. The associates’ bullpen sat in the northwest third of the floor, the house’s Wu Gui sector, quarrel ground, and the filing and server rooms sat in the southeast, squandering the house’s best ground on functions that visit nobody.
The recommendations, and the reason this case is a teaching staple: swap the bullpen and the filing function, which cost the firm two weekends of internal moves and nothing else; put each partner’s client chairs on the visitors’ hostile bearings rather than the hosts’, a detail from the classical application layer that most tutorials never mention and negotiation-savvy clients love; and move the junior associates’ desks into Yan Nian ground, the relationship star, because the firm’s actual problem was that its youngest lawyers had no senior time and no ground that made conversation easy. Twelve months later the attrition had halved, the partners credited the audit in the way partners credit things, grudgingly and with invoices attached, and I have told the case hundreds of times since because the lesson generalises: the building was helping the people who least needed help, which is the default failure mode of every organisation I have ever walked into, compass or no compass.
Case File: The Corner Unit That Argued With Itself
The second case is an apartment, and it is here for the readers who own awkward homes, because awkward homes are the majority. A couple, both professionals, one East group and one West group, in a corner unit that genuinely faced two ways, southwest toward the view and southeast toward the corridor network, the split-orientation building from the apartment section behaving exactly as predicted. The disputes: whose map governed the master bedroom, whether the study should follow the wife’s career code or the husband’s, and a growing argument about the desk in the living room that was technically the husband’s office and emotionally everyone’s problem.
The resolution, layer by layer, because the couple asked for the reasoning and it is the reasoning that generalises. The unit was read as two wings, and each wing got its own map; the master bedroom sat on the view wing’s Tian Yi ground for the wife, whose health question was the live one, and the bed head was rotated to her Yan Nian bearing, which, checked against the husband’s map, turned out to be his Fu Wei bearing, the overlap the earlier section promised usually exists. The study went to the corridor wing, on the husband’s Sheng Qi ground, and the living-room desk, the real cause of the argument, was removed entirely and replaced by a proper desk in the study, the placement fix that changed the marriage being, in the end, a door that closed. The lesson this case teaches: most feng shui disputes are territory disputes wearing compasses, and the map’s real value is that it turns the argument into an allocation, and allocations, unlike arguments, end.
Case File: The Restaurant That Could Not Keep a Kitchen
The third case is the stove story, and I keep it because it converted me a little further than I expected. A restaurant, family-run, good location, consistent reviews, and a pattern the owner could not break: kitchen staff turning over every few months, each departure taking recipes and rhythm with it, the classic hospitality death loop. The audit found the kitchen occupying the building’s Jue Ming sector, the worst of the eight, with the head chef’s station on the sector’s worst bearing for the chef’s own life trigram, and the walk-in cold room, the heaviest yin function in the building, sitting in the dining room’s Sheng Qi ground, where the money should have been entering.
The recommendations: the chef’s station moved within the kitchen to the one position that faced his personal Tian Yi bearing, the cold room and the dry-store swapped, putting the storage mass in the Jue Ming sector where the containment rule wanted it, and the staff table, where the family ate together before service, moved to a small Yan Nian pocket near the entrance, on the theory that the household that eats together stays together, which is folk wisdom, form school and Eight Mansions agreeing with each other for once. The staff turnover halved over the following year, the owner attributed it to the chef’s station move, the chef attributed it to being able to see the door, and I recorded both attributions and made no correction, because a result with two honest explanations is still a result, and the humility in that sentence is the most professional thing I can teach in this case file.
What the Case Files Have in Common
Three cases, three industries, one pattern, and the pattern is the teaching. In every building I have audited, the fixed functions were in the wrong places not because the owners were careless but because the building’s designers optimised for plumbing, light and rent, not for the lives inside, and nobody with a map had ever checked the allocation against the actual household. The audits did not change the buildings; they changed where the people and functions sat inside them, the cheapest possible intervention in real estate, and the outcomes moved enough to be reported, attributed and remembered. That is the honest claim of this school, stated after years of practice: allocation matters, dwell time compounds, and a two-metre desk move is the highest-return renovation in the building. If the rest of this site teaches you the timing layers that surround that claim, this page has taught you the claim itself, and the case files exist to show it working with the receipts attached.
A Short History of the School
Eight Mansions is not a recent invention, and its lineage deserves a paragraph because the internet treats it as either eternal or invented, and it is neither. The logic roots deep in the classical corpus: the life trigram assignment for people traces to the wandering star material associated with the eight trigram palaces, and the sitting-direction method for buildings is codified in the Ba Zhai Ming Jing, the Eight Mansions Bright Mirror, a text that matured in the Qing period and pulled together older compass-school practice. The text’s achievement was systematisation: take the trigram assignments, the element cycles and the star logic that existed in fragments, and compress them into a procedure a working surveyor could execute, which is why the school spread the way practical systems spread, through use, not decree.
The modern lineage is a Malaysia and Singapore story as much as a China one. The school’s twentieth-century revival ran through the overseas Chinese communities, with practitioners in Malaysia and Singapore publishing the books and running the practices that kept the method in daily professional use while the mainland’s tradition went through its disruptions, and the English-speaking feng shui wave of the late twentieth century carried the school to the West with more enthusiasm than accuracy. The version I teach is the classical procedure, with the modern building stock, apartments, towers, corner units, factored in honestly, and with the industry’s fear layer stripped out, and students who learn it here are learning the same arithmetic a Qing surveyor would recognise, delivered for homes that surveyor never imagined.
How to Learn This Properly, the Honest Path
Step one you have already taken: this page, the whole method, the tables, the traps, the case files. Step two is the practice assignment I set every class, and I set it because it converts readers into practitioners: take your own home, draw the floor plan to rough scale, take three compass readings, resolve the sitting, compute your life trigram, and mark all eight sectors with both maps, house and personal, on one sheet. That exercise, one evening, teaches more than a month of reading, because every ambiguity you meet is an ambiguity the tutorials forgot to mention, and you will meet all three of them, boundary readings, split facades, hostile master bedrooms. Step three: audit a friend’s home for free, with the rule that you state your confidence on every call, because the discipline of saying where the method is sure and where it is guessing is the whole difference between a practitioner and a personality.
Step four, for the reader who wants the professional stack: the deeper systems, in the order this site teaches them. The five elements, which is the grammar. BaZi, which reads the person. Flying Star, which reads the building’s time. Ze Ri and Xuan Kong Da Gua, which read dates. Qi Men Dun Jia, which reads the hour and the tactic, the system this practice is known for and the one I teach at depth in English. Each has its own guide on this site, free, and the links run from the library section at the foot of this page. The tradition’s full stack took me years, and it was years well spent, and the modern reader’s advantage is that the stack is now written down in one place by one voice, which is the gap between how I learned and how you can.
Teaching in English, a Word About This Practice
A note on why this site teaches the school in English, because students ask and the answer is part of the method’s future. The classical material is mostly in Chinese, and the English-language feng shui shelf is dominated by translations of translations, often stripped of the arithmetic and sold as lifestyle, which is why serious bilingual practitioners quietly distrust the English market. I teach in English because the tradition’s next generation is global, my students are in Singapore, Kuala Lumpur, Sydney, Toronto, London and everywhere the diaspora scattered to, and because a system that cannot state its method in a working language cannot survive being handed over in it. The result on this site: every term carries its Chinese original, the arithmetic is shown rather than asserted, and the skeptical reader is invited rather than managed, because a tradition confident in its method does not need to gatekeep it.
That is also the standing promise of this page’s existence. The thin listicles that rank above honest guides for these searches sell one lucky direction and a paragraph of fog; this page gives the entire school, the tables, the traps, the case files, and the links to everything deeper, because the strategy of this whole site is that the reader who checks the work becomes the client who trusts the practice, and every year of this business has confirmed it.
A Reading List From the Practice
The classical texts, for the reader who wants the sources behind the method. The Ba Zhai Ming Jing, the Eight Mansions Bright Mirror, the school’s founding codification. The Yi Jing, the Book of Changes, the trigrams’ root text, which this site also teaches in its own guide. The classical five element material from the medicine and metaphysics corpus, the grammar behind every star rating. The modern shelf, offered with one warning: read it after the classical method, not before, because the modern market’s confusions are easier to spot when you can already compute the tables yourself, and the confident wrong book is the genre’s biggest hazard. And this site’s own companion guides, the trigram reference, the five elements set, the Flying Star guide, the date selection method and the Qi Men Dun Jia hub, which exist because the tradition is a stack and this page is the first floor, and the whole building is linked at the foot.
Frequently Asked Questions
How do I find my life trigan, quickly and correctly? The safe route is the arithmetic in the third section of this page with the Li Chun rule applied, or the free birth data tools on this site. The unsafe route is any random online calculator that does not state the Li Chun boundary, and you now know the two anchor checks, 1984 male computing to 6 and 1992 female computing to 2, that separate the reliable from the rest.
What if my house and my personal group clash? Read the compatibility section, and the short answer is allocation: you work at sector level, place your personal bearings inside the rooms you control, and the mismatch costs comfort rather than forbidding the address. The mismatch case is the most common audit in modern practice, and the fear-based version of the industry has made more money from it than any other configuration, which is why this page spends its word budget on the working version instead.
Does Eight Mansions work in apartments and offices, or only houses? The method was built for houses and extends to apartments through the convention this page teaches: towers get read at tower level, units get their own internal map for the space you own, and the two-layer reading resolves the buildings the classical authors never saw.
Which is better, Eight Mansions or Flying Star? Wrong question, correct question: which answers your need. Eight Mansions allocates space and holds for decades; Flying Star times the building’s periods and years. Professionals run both, and the comparative section of this page gives the exact division of labour.
Can I fix a bad sector with a mirror, crystal or ornament? The classical method fixes bad sectors with containment and use, and the ornament market is an industry, not a tradition. The remedial section of this page lists what actually moves the needle: physical change, use change and time.
My main door is on a bad sector. Should I move? No, and the classical authors, who also could not always move doors, say so through the method itself: the door is managed, kept unobstructed and clean, and the rest of the building carries the allocation load. Moving house over a door sector is a decision you make for reasons a compass cannot see, and any practitioner who tells you otherwise is auditioning for the commission.
Do both partners in one bed need the same direction? The bed head follows the partner whose stability the household most needs, and the good directions of any two trigrams usually overlap at least one bearing. The couple’s section covers the negotiation, and the negotiation is usually easier than couples expect.
Should I update my map every year? Your life trigram never changes, your house’s sitting never changes, and the annual updates that circulate each February are the Flying Star and year-god overlays, which this page separates from the map itself. Recompute the map when you move, renovate or change the sitting, and let the calendars handle the weather.
Is Eight Mansions against my religion? The school is arithmetic over directions and birth data, with no deity, worship or belief requirement in the method itself, and the faithful and the skeptical both practice it. The faith questions deserve a longer answer than a FAQ line, and the comparative and skeptic sections of this page carry the discussion respectfully.
How much does a professional audit cost, and what should it include? Fair question, and the honest answer varies by market and scope, so the professional answer is the deliverable list: an on-site or plan-based sitting determination, both maps computed and shown, a written report with the three placements ranked, the boundaries stated, and the reasoning visible enough that you could check it. This practice’s consultation page prices its own audits plainly, and the red flag checklist above tells you what to reject at any price.
Can I combine Eight Mansions with Qi Men Dun Jia date selection for a house move? Yes, and it is the standard full-service combination: the audit chooses rooms and bearings, the QMDJ layer selects the hours, and the time-layer section of this page shows the handover. The site’s calculator and date selection guides cover the practical path.
What is the single most common mistake you see in client charts? Without competition, the Li Chun boundary, January and early-February births computed against the wrong year, which flips the group itself and therefore every downstream placement. The second most common is facing taken for sitting, which mirrors the whole house. Both are in the mistakes section with their fixes, and the frequency of both is why this page is as long as it is.
The Eight Mansions Glossary
Ba Zhai (八宅). Eight Mansions, the school this page teaches, the name referring to the eight trigram mansions a building can sit in.
Ming Gua (命卦). The life trigram, the personal code computed from birth year and sex, one of the eight trigram codes, fixed for life. The arithmetic and the Li Chun boundary are in the third section.
Zhai Gua (宅卦). The house trigram, computed from the building’s sitting direction, the code that generates the house’s own map. The sitting-versus-facing procedure is in the fifth section.
East group. The trigram set Kan, Zhen, Xun and Li, codes 1, 3, 4 and 9, whose elements feed each other. East group people harmonise with East group houses, and within any house, East group sectors are their supportive ground.
West group. The trigram set Kun, Gen, Dui and Qian, codes 2, 8, 7 and 6, same logic mirrored. The two groups are chemistries, not rankings.
Sheng Qi (生气). Generating breath, the best wandering star, income and momentum ground. Desk seats, doors and revenue roles. Not a bedroom star for anyone recovering.
Tian Yi (天医). Heavenly doctor, the health star, recovery ground. Bedrooms for the unwell, reading chairs, and the classic bed-head bearing.
Yan Nian (延年). Prolonging years, the relationship star, marriage and longevity ground. Master bedrooms for couples, dining tables, conversation corners.
Fu Wei (伏位). Stable seat, the calm star, study and consolidation ground. Study desks, meditation, children’s workrooms, and the gentle bed-head alternative.
Huo Hai (祸害). Mishaps, the mildest hostile star, accident and leak ground. Containment: storage, laundries, machines.
Wu Gui (五鬼). Five ghosts, the quarrel star, office politics and betrayal ground in the classical language, interpersonal friction in the modern audit. Containment, never a desk.
Liu Sha (六煞). Six killings, the legal star, litigation and slow-damage ground. Containment, and in the classical application layer, where the visitor chairs sometimes go, which is the application detail partners enjoy most.
Jue Ming (绝命). Absolute end, the worst hostile star, exhaustion and attrition ground. Toilets, storage and plant; never a bed, a desk or a main entrance if any alternative exists, and if none exists, escalate to the time layer honestly.
Sitting (坐). The back, the resting side of the building, the yin side whose trigram names the house. Determined by two tests, the door-and-street test and the window-and-light test, resolved in the fifth section.
Facing (向). The front, the yang side, the direction the building looks. Always opposite the sitting on the compass wheel, in this school’s usage.
Li Chun (立春). The solar beginning of spring, February 3rd to 5th, the boundary of the feng shui year for every calculation in Chinese metaphysics. January and early-February births belong to the previous year. The single most common source of wrong charts.
The twenty-four mountains (二十四山). The 15-degree compass slices, three per trigram, twenty-four around the wheel, the resolution layer for boundary readings and the deeper schools.
The five elements (五行). Wood, fire, earth, metal, water, their generative and control cycles, the grammar from which every star rating is computed. This site’s five element guide covers the full system.
The bagua (八卦). The eight trigrams, the three-line codes whose directional, elemental and associative properties carry the entire method.
Containment. The school’s answer to hostile sectors: dirty, draining or machine functions on hostile ground, where the hostility spends itself on sewage and storage rather than on sleepers.
The group test. The compatibility check between a person’s group and a building’s sitting group, a ranking input at purchase, never a verdict at eviction.
The house gua map. The eight-sector map of a specific building generated from its sitting trigram, the fixed layer every audit starts from.
The personal map. The same eight-star table generated from a person’s life trigram, applied to personal placements, beds, desks, chairs, inside whatever rooms the building provides.
Flying Star (飞星). The sibling timing school, period charts and moving stars, covered in its own guide on this site and compared honestly in the schools section.
Tai Sui (太岁). The year’s presiding direction, a construction caution zone, released at the next Li Chun, and the most monetised concept in the fear branch of the industry.
Qi Men Dun Jia (奇门遁甲). The hour-board tactical system this practice is known for, the layer Eight Mansions hands dated decisions to, with its own hub and calculator on this site.
The Eight Mansions Library on This Site
This page is the reference for the school, and the deeper layers live in their own guides, free, all on this site. The trigram foundations are covered from the Qi Men Dun Jia angle in the trigram guide, which uses the same eight characters as palace logic, and the five element cycles that generate every star rating have their own full set of guides on the site. The timing schools: the Flying Star guide for the building’s periods and years, the date selection method for movable dates, and the Qi Men Dun Jia hub for the hour-level tactical layer, including the free calculator that plots hour boards. The person layer: the BaZi consultation guide reads the person’s own structure and seasons at full depth, and the fortune telling consultation guide runs the reading model end to end. The birth years library lists the exact Li Chun boundaries for every year from 1920 to 2030, which is the cross-reference this page’s boundary rule needs. The links below are the reading path I recommend after this page.
The eight trigrams, meaning and definition, the same bagua from the QMDJ angle. The Qi Men Dun Jia hub, the system this practice teaches at depth. The free QMDJ calculator, hour boards plotted on demand. QMDJ date selection, the method for movable dates. The BaZi consultation guide, the person layer at full depth. The fortune telling consultation guide, the full reading model. The birth years library, every year’s Li Chun boundary. Booking a consultation, for readers whose buildings outrun the page.
Reading Order for the Full Stack
For the reader who wants the whole tradition rather than one school, the order I teach, and the reason for the order. Start here, Eight Mansions, because it is complete in an afternoon and gives you the compass, the trigrams and the discipline of checking. Then the five elements, the grammar, best learned after you have seen it working in star ratings rather than as an abstract wheel. Then BaZi, the person layer, because buildings serve people and a person’s own seasons change which rooms matter when. Then Flying Star, the building’s time, which makes the static map come alive across decades. Then the date layer, Ze Ri and the hour systems, and finally Qi Men Dun Jia at depth, the tactical summit, where the tradition stops being a map and becomes a clock and a chessboard.
The order is also the difficulty curve, deliberately: each stage uses the vocabulary of the previous one and adds one new instrument. Students who try the reverse order, starting with QMDJ boards because they are spectacular, learn a lot of squares and no compass discipline, and the results read accordingly. The slow stack is the fast stack, a sentence that was true in every business I ran before this one and remains true in this one.
If You Want the Audit Done for You
Everything on this page is free and complete, and some readers will still want the audit done professionally, which is what the consultation side of this practice is for, and the honest scope is this: a sitting determination taken properly, both maps computed and shown, the three placements ranked for your household, the written report with reasoning you can check, and the escalation to the timing layers if your question needs them. Sessions run online worldwide and in person in Singapore and Kuala Lumpur, the report is delivered in plain English, and the boundaries stated at the top of this page are stated again in the engagement letter, because the practice’s policy is that the reading’s honest limits are part of the product, not fine print under it.
What I would ask of you if you book, or if you self-audit from this page, is the same request either way: test it. Move the desk, rotate the bed head, run the arrangement for a season, and note what you notice, because the tradition is checkable and this page exists to be checked, and the clients who check are the ones whose results I can report in case files like the ones above, with the attributions intact and the humility unedited. That is the whole practice in one paragraph: arithmetic shown, boundaries stated, results observed, and no instalment plans, ever.
The Ninety Days After Your Audit
What to actually do with the map once you have it, the same brief I give audit clients. Days one to seven: make the free moves, the desk rotation, the bed head change, the mirror, the door path, and change nothing else, so you can attribute what follows. Weeks two to eight: live in the arrangement, keep a short weekly note if you are the noting kind, sleep quality, friction at the desk, the room’s arguments, because ninety days of observation is the audit’s proof stage and most clients skip it. Week eight: review, and if a placement genuinely did nothing, say so, to yourself or to me, because placements that do nothing are data, and the practice improves by keeping the honest ledger, not by keeping the wins only.
And the final calibration, the one I close client briefings with, offered to you the same way. If the map helps, use it, and if it does not, you have lost one evening and gained a floor plan you finally understand, along with the compass habit, which is worth keeping for the viewing of your next building regardless. The tradition does not need your faith. It needs your door, your compass and your attention, and it repays all three, which is more than most systems I priced in thirty years of business, and I have priced a great many.
Your Trigram, Your Life: The Four East Codes
This section and the next read each life trigram the way I read it for clients: the code, the group, the four good and four bad bearings, and the practical portrait of what the tradition observes in each type. Treat the portraits the way the school itself treats them, as tendencies written from centuries of observation, checked against real people, never as verdicts on anyone’s character.
Code 1, Kan water, the north, East group. Good bearings: Sheng Qi southeast, Tian Yi east, Yan Nian south, Fu Wei north. Hostile: southwest, northwest, northeast, west. The water person in the classical portrait is the deep one, reflective, resourceful under pressure, and prone to worry loops, and the practical readings I notice in audits: Kan people profit most from their Fu Wei bearing, their own home direction, more than most codes do, and they are the trigram whose charts most often show sleep as the live question, so the bed-head work matters first for them.
Code 3, Zhen wood, the east, East group. Good bearings: Sheng Qi south, Tian Yi north, Yan Nian southeast, Fu Wei east. Hostile: west, northwest, southwest, northeast. The thunder portrait is the initiator, restless, quick-starting, and the classical literature calls the Zhen person the eldest-son energy regardless of sex, meaning the one who moves first. Audit observation: Zhen people tolerate a mismatched building better than most because they simply outwork it, and the placement that changes their reports fastest is the desk bearing, not the bed.
Code 4, Xun wood, the southeast, East group. Good bearings: Sheng Qi north, Tian Yi south, Yan Nian east, Fu Wei southeast. Hostile: northeast, southwest, west, northwest. The wind portrait is the diplomat and the networker, gentle-moving, persuasive, and the classical texts credit Xun with the most luck through other people, which in business language means referral income, and Xun clients are the ones whose Yan Nian bearing placements, the relationship star, produce the most commented-on results. The wind person’s caution in the literature is indecision, and the desk on Fu Wei, their own home bearing, is the classical study fix for it.
Code 9, Li fire, the south, East group. Good bearings: Sheng Qi east, Tian Yi northwest, Yan Nian southwest, Fu Wei south. Hostile: north, northeast, west, southeast. The fire portrait is the visible one, expressive, charisma-carrying, quick, and the classical association with the eye and the heart shows up in the portrait as intensity. Audit observation: Li people are the trigram most sensitive to hostile working seats, in the sense that their reports change most after desk moves, and least sensitive to hostile bedrooms, in the sense that they sleep anywhere, and the map work for fire codes is almost always about where they work, not where they sleep.
The Four West Codes
Code 2, Kun earth, the southwest, West group. Good bearings: Sheng Qi northeast, Tian Yi west, Yan Nian northwest, Fu Wei southwest. Hostile: south, southeast, east, north. The earth-mother portrait is the load-bearer, patient, absorbing, the one the household leans on, and the classical literature is unusually direct about the Kun person’s risk: giving until empty. The practical readings for Kun codes concentrate on the Tian Yi bearing and health ground, and the bed-head change on the western bearings is the placement I recommend first for this code, because the portrait’s whole pattern rests on the mother-rests question.
Code 6, Qian metal, the northwest, West group. Good bearings: Sheng Qi northeast, Tian Yi west, Yan Nian southwest, Fu Wei northwest. Hostile: south, east, southeast, north. The heaven portrait is the authority figure, decisive, structural, the executive trigram, and the classical texts call Qian the father energy, the one who commands. Audit observation: Qian people are the least likely to book an audit and the most likely to re-arrange a whole floor after one, because the portrait’s decisiveness cuts both ways, and the practitioner’s job with a Qian client is to slow the implementation down, not to motivate it.
Code 7, Dui metal, the west, West group. Good bearings: Sheng Qi northwest, Tian Yi southeast, Yan Nian northeast, Fu Wei west. Hostile: east, south, southwest, north. The lake portrait is the speaker, charming, expressive, sales-gifted, and the classical association with the mouth and with joy is the portrait’s centre. Dui people in audits respond fastest to conversation-ground placements, the dining table and the reception seats, and the classical texts’ caution for the lake person is pleasure-spending, which the wealth tradition handles in its own guides and which this school handles by keeping the money desk on Sheng Qi ground, northwest for this code.
Code 8, Gen earth, the northeast, West group. Good bearings: Sheng Qi southwest, Tian Yi northeast, Yan Nian northwest, Fu Wei west. Hostile: north, south, east, southeast. The mountain portrait is the still one, steady, slow-starting, immovable once moving, and the classical texts call Gen the youngest-son energy, the one who arrives last and stays. Audit observation: Gen people are the trigram whose results arrive latest and last longest, which makes them the trigram most likely to abandon a placement too early, and the professional advice I write into every Gen client’s brief is a single sentence: give the arrangement a full season, your own code’s patience is the method’s proof.
Eight Mansions for Businesses, the Full Commercial Layer
The commercial applications deserve their own space because businesses are households with revenue, and the school’s commercial layer is where my thirty business years and this tradition overlap most directly. The building-level reading is the same as for homes: the sitting trigram, the house map, the group test, and the first commercial question is always the same one I ask a family, who spends the most hours where, because dwell time is the currency this school trades in. The shop or office answer writes its own brief: the principal’s seat, the revenue team’s desks, the customer-facing positions, the negotiation table, and the back-of-house functions in containment order.
The negotiation table deserves the paragraph, because it is the commercial detail the classical application layer keeps and the modern tutorials lose. The old texts, which served courts and merchant houses, read the host-and-guest seating with the same star logic as a bed or a desk: the host sits supported, back to a wall, on a bearing that feeds their own code, and the guest chairs sit where the visitor’s own map would be hostile, which, stated plainly, is the same seating logic every boardroom in the world independently evolved, senior back to the wall, visitors facing the light. The school’s contribution is not the discovery, it is the arithmetic that lets you replicate it for any specific visitor, and business clients who receive the brief for their own meeting rooms report the same thing family clients report about dining tables: the room starts working for whoever briefed it.
Business Types, Read One by One
Retail. The entrance is the intake, the counter or service position is the revenue seat, the display is the attention engine, and the stockroom takes the containment ground. The proprietor’s standing bearing during trading hours is the highest-leverage placement in the building, and the retail audits that moved it, the Kuala Lumpur case earlier in this page is the standing example, produced the most repeated-business referrals in my commercial file.
Offices and professional firms. The partner layer and the staff layer read like a family: revenue roles on Sheng Qi ground, support roles on stable ground, the server rooms and storage on the hostile sectors, and the staff bullpen question from the law firm case is the office audit’s most common finding, the most-used ground allocated to the least-revenue function, a pattern I have now seen in every professional services building I have walked.
Restaurants and hospitality. The kitchen is the health engine, the stove logic intact, the dining floor is the conversation engine, Yan Nian ground, and the entrance is the intake. The hospitality failure mode is the restaurant case’s cold room finding, the heaviest yin functions sitting on the money ground, and it is the first thing I look for in any food business.
Clinics and practices. The waiting room wants convivial ground, the treatment rooms want Tian Yi ground for obvious reasons of the tradition’s own logic, and the practitioner’s own desk wants the practitioner’s personal map, not the house’s, because the person doing the healing is the building’s most valuable equipment.
Factories and logistics. The office block reads as an office, the production floor reads by form, movement, light and flow, and the compass layer contributes the office placements, the gates and the groundbreaking dates, the last of which hands over to the date systems as described in the time-layer section.
The Business Case for the Skeptical Managing Director
The paragraph I give boards, because I have sat on boards myself and know the room. This method costs a fraction of one consultant week to apply, it relocates furniture that was going to be rearranged anyway, it encodes decisions that plausible heuristics, seating, light, sight-lines, would partially recommend regardless, and it adds a layer of consistency, the same map applied next quarter and next year, which heuristics never deliver. The downside case is that nothing measurable changes and you have lost an afternoon, and the upside case is the law firm’s attrition curve. In thirty years of business I have paid for many frameworks with worse expected value, and I say that as the person selling this one, which is exactly why I say it with the numbers left in and the boundaries stated, because the reader who checks is the client who stays.
QMDJ Feng Shui, Where the Tactical Layer Joins the Compass
A closing bridge to the school this site is known for, because Eight Mansions and Qi Men Dun Jia are the two ends of the practical stack I run daily. Eight Mansions gives the building its stable map, and QMDJ gives any chosen hour its tactical board: doors, stars, gods and formations plotted for the moment, read for the specific action. The classical tradition has always used them together, the imperial strategists who needed both a camp and a hour for the attack, the merchant houses that chose the shop and then chose the signing hour, and the modern reading preserves the division exactly: space from the mansion, time from the board.
For the reader whose building is audited and whose question has now become dated, the next step is the QMDJ layer, and this site carries it in full: the hub that explains the system, the calculator that plots hour boards free, the date selection guide that turns boards into calendars, and the course for readers who want the machine, not just the readouts. The Eight Mansions page you are reading is the ground floor of the stack, and the tradition’s honest promise is that the ground floor is useful alone and better with the floors above it, which is the architecture of this entire site, and now you have seen it stated from the bottom.
The Professional Audit Protocol, Start to Finish
How an audit actually runs, so that professional work is demystified the same way the method was. Stage one, before the visit: the brief, which means the client’s questions in priority order, the floor plan, and the birth data of everyone whose placements matter, with the Li Chun rule applied at intake because it is the first place errors enter. Stage two, on site: the building walk, before any instrument, eyes first, form before compass, and then the compass work, three or more readings from different interior positions, the outside shot for the building’s mass where the site allows, and the sitting resolved from the two facing tests. Stage three, the computation: house map, personal maps, the group test, and the three placements ranked, all shown to the client live, because the audit that hides its arithmetic is an audit asking to be trusted rather than checked, and this practice does not ask that.
Stage four, the brief-back: the client hears the reading while standing in the rooms it concerns, which is a discipline I keep because readings delivered in a conference room lose the building, and the client’s own eyes need to watch the practitioner point at the wall the bed-head should face. Stage five, the report, delivered in writing within the week, the maps drawn, the reasoning visible, the boundaries stated, the ninety-day protocol attached. The whole engagement is a day of work and a document, and the industry’s habit of stretching it into ceremonies and follow-up escalations is a business model choice, not a method requirement, and you now know the difference.
Questions Worth Bringing to Any Practitioner, Including Me
The intake questions that make readings better, the same way good patient questions make consultations better, offered so that your engagement, with me or with anyone, starts from the strong side. Bring your live decisions, the lease expiring, the renovation scheduled, the child’s exam year, the hiring plan, because placements made in a vacuum decay and placements attached to decisions stick. Bring your skepticism, openly, because a good practitioner calibrates to a checking client rather than performing for a believing one. Bring the household’s birth data accurately, which sounds basic and is the single biggest data failure in practice. And bring the question the fear-branch never wants asked, which is: what is the cheapest change that could plausibly work, and what is the evidence standard for deciding it did. That question, asked in a first session, sorts practitioners faster than any checklist, and I mean it as a compliment to the reader who asks it.
The Year-Round Routine, a Maintenance Calendar
The maintenance view, for readers who want the method as a habit rather than an event. February after Li Chun: the annual overlays checked, the five yellow and illness sectors noted, the Tai Sui construction cautions marked on the household calendar, ten minutes. Quarterly: the three placements walked once, door, bed, desk, because houses drift, furniture migrates, and the quarterly walk is how a map stays a map. At every purchase, lease or renovation: the ten-minute group test before money moves, which is the highest-leverage ten minutes in the whole tradition. And once, when you move into any building that matters: the full protocol, this page as the manual, or a professional audit if the stakes justify it. The routine is deliberately light, because a system that demands weekly rituals is a system designed for the seller’s calendar, not the reader’s life, and the school’s classical authors, who were surveyors with other buildings to reach, would have approved of the brevity.
The Tradition and the Internet
A last observation before the closing sections, because you likely arrived here through a search that also returned the genre’s worst work, and you deserve a plain account of the landscape. The English-language Eight Mansions content online is dominated by three failure modes: the lucky-number listicle, which truncates the school to a birth-year table and a direction, with the Li Chun rule lost entirely; the fear funnel, which discovers a hostile sector and walks you toward the shop; and the mashup post, which mixes Flying Star remedies into a mansion map and sells the confusion as depth. This page was built as the antidote to all three, the complete method, boundaries stated, arithmetic shown, no shop attached, and it will rank against the failure modes the way every honest guide has to rank, by being the reference people keep returning to. If it helped you, the useful action is the one this site always asks for: use it, check it, and if you ever cite it, cite the parts that showed their work.
Three Floor Plans, Walked
Three compact walkthroughs, different building types, so you can watch the whole method execute end to end, the way exam answers work. Walkthrough one, the east-facing executive flat: sits west, a Dui house, West group; the main door opens to the north of the unit’s entrance hall, sitting on the house’s Tian Yi ground, which is a quiet strength; the master bedroom sits in the northeast, Sheng Qi ground for the house, and the owners are both West group codes, so the house, the room and the people agree, and the audit’s only work is the bed head, rotated from due east, hostile for both codes, to the southwest, Yan Nian for both, an overlap found by checking the tables rather than hoping for one.
Walkthrough two, the west-facing resale terrace: sits east, a Zhen house, East group; the kitchen sits in the southeast, the house’s Sheng Qi ground, which the containment logic would rather spend elsewhere, but renovations are not on the table, so the stove work happens inside the kitchen, the range sitting on the sector’s worst corner for the wife’s code while facing her Tian Yi bearing, the classical inversion applied where the floor plan allows; the two children’s rooms sit south and north, Yan Nian and Fu Wei ground respectively, and the boy in the exam year takes the north room’s Fu Wei desk facing his own Sheng Qi, south. Walkthrough three, the corner shophouse with the office above: two floors, two readings, the shop floor sits east by its own door logic, the office floor sits south by its own window logic, and the owner’s single-page brief carries two maps and one sentence of hierarchy, the revenue floor’s placements take precedence over the office’s, because the business pays for both floors. Three buildings, three pages of notes, and the pattern across all three: the school’s work is almost always three placements and a sentence of judgment, and the professionals who produce forty-page reports are padding, not auditing.
What This School Is, Stated One Last Time
Eight Mansions is the tradition’s most portable instrument, a compass-and-arithmetic method that allocates the space you already own to the life you actually live, and this page has given you the whole of it: the trigrams, the two groups, the life trigram with its boundary rule, the eight wandering stars with their honest rankings, the house trigram with the sitting tests, the big three placements, the room-by-room brief, the commercial layer, the time overlays, the case files with their attributions intact, and the boundaries, stated before you could discover them the expensive way. The method is checkable by design, it was built by people who checked, and it survives in this practice because thirty years of business taught me to keep only the instruments that repay checking.
If you take one thing from this page, take the sequence: form before compass, allocation before ornament, the map before the calendar and the calendar before the hour. If you take two things, add the Li Chun rule, because it is the difference between your chart and a wrong chart, and wrong charts are the genre’s most expensive product. And if this page earned your attention through to this paragraph, the library section has your next step, whatever layer you are ready for, all free, all built the way this one was built, with the work shown.
About the Practice Behind This Page
This guide is written by Dougles Chan, a Qi Men Dun Jia educator and lineage founder from Singapore, and the biography that matters for this page is not the mystical one. I spent over thirty years in business, running companies, recruiting and advising owners across Singapore, Malaysia and the wider region, and I came to Chinese metaphysics the way an engineer comes to a machine: through the checking. The practice today audits buildings, reads charts and teaches the full stack in English, in person in Singapore and Kuala Lumpur and online everywhere else, and the teaching philosophy is the one you have just read: arithmetic shown, boundaries stated, no fear sold, no instalment plans, ever. The consultation page carries the formats and the plain pricing, the course page carries the QMDJ curriculum for readers who want the machine, and this page, the Eight Mansions guide, is free, permanently, because the method’s own authors wrote it for people who could not afford a surveyor, and I honour that intention the modern way, with a complete reference that outranks the listicles.
The Five Element Layer in Placement
The wandering stars are computed from the five elements, and the elements also give the placement layer its physical vocabulary, so this section completes the circle: how to actually support a good sector and weaken a bad one using real materials, colors and functions. The logic is the same cycles you met early on. A Sheng Qi sector whose star is wood is strengthened by wood and water, green and blue tones, plants, books, upward-growing shapes, and weakened by metal objects, white and metallic palettes, and heavy cutting tools stored there. A Tian Yi sector that lands on earth trigram ground responds to fire and earth, warm tones, ceramics, solid low furniture, good light. Compute the sector’s element from its trigram, then support that element with what you place there, and the same table reads in reverse for the containment rooms, where you want the hostile sector’s function to spend, not to flourish.
The honest calibration, before the decor industry reads this section the wrong way: the element layer is the weakest of the school’s levers, and I rank it last in every audit, behind sector allocation, bearings and form. Moving your desk to Sheng Qi ground does more than any object placed anywhere, and the client who skips the move and buys the objects has bought furniture with better marketing. The element layer earns its place in two specific jobs: tuning a room you cannot rearrange, and marking the rooms that matter, a red-toned accent where you want activity, a calm earthy palette where you want rest, which is interior design agreeing with the school, and the agreement is real because both traditions observed the same animals, humans, responding to the same rooms.
Colors, Shapes and Materials, the Practical Table
The working table, written for use rather than for mystique. Fire: reds, oranges, deep warm palettes, triangular and pointed forms, strong direct light, activity and visibility, use where you want energy, avoid where you want sleep. Earth: ochres, tans, warm neutrals, square and low forms, ceramics, brick, stone, use where you want stability and gathering, the dining room logic. Metal: whites, greys, metallics, round forms, the efficiency palette, use for precision rooms, studies, surgery-clean kitchens, avoid in excess where you want softness. Water: blues, blacks, glass, reflective surfaces, flowing forms, use sparingly and deliberately, one strong water feature beats five token ones, and never under a bedroom, which is form-school advice the compass schools adopted after losing enough arguments. Wood: greens, living plants, vertical forms, books, growth objects, the default vocabulary of a healthy room, and the element most sectors tolerate, which is why plants are the school’s most forgiving furniture.
The shapes column is the underrated half of that table, and I flag it because clients over-index on color and never notice shape. A hostile sector furnished with low, square, stable pieces reads quieter than the same sector furnished with sharp, busy, angular ones, whatever the paint says, and a Sheng Qi office furnished round, soft and muted is sabotaging its own star quietly. The school’s classical authors worked in an age of furniture rules, and the modern reader can decode those rules as this table: elements, colors, shapes, functions, arranged to agree with the map.
Renovation Timing, the Pacing Advice
When the placements need construction to happen, the timing advice of this school is short and practical. Sequence the work from the big three outward: door, bed, stove, then everything else, because the big three carry the reading and the rest is finish. Respect the year cautions, Tai Sui, Sui Po and the Three Sha sectors, for heavy digging and major demolition, which in practice means checking one table before scheduling the contractor, and the table is in the time-layer section above. If the renovation is small, cosmetic, interior and does not break ground in the flagged sectors, the cautions do not apply, and the industry that tells you a coat of paint angers the year god is the fear branch selling calendar pages. For the move-in hour and the re-opening hour, hand the decision to the date layer as described earlier, and for everything between, the rule I actually practice: pace the work, keep the site orderly, and let the building finish before you read it, because an audit of a half-renovated house is an audit of dust.
When the Method Says Walk Away
One section the honest version of this school requires, because every other long guide omits it. The configurations where my advice stops being allocation and becomes a recommendation against the building itself, and they are rare, so stated exactly. A main entrance that cannot avoid sitting in the house’s Jue Ming or Liu Sha ground while also being dark, cramped or obstructed, because compass weakness and form weakness compounding at the same mouth of the building is the one configuration the classical texts treat as structural. A master bedroom that offers no bed position free of hostile bearings, hostile sector and a beam or mirror problem at once, for years of occupancy, with no other room to take. And the case I meet most in practice, the building whose form problems, noise, vibration, dampness, hostile adjacent land use, are severe enough that no interior map rescues the daily experience, in which case the honest audit ends with the sentence I have delivered exactly four times in this practice: the problem is the building, and no placement fixes a building.
Those verdicts are less than one in twenty audits, and I give them the prominence they deserve precisely because they are rare: a method that only ever says yes is not a method. The reader’s protection, in audits and in this page alike, is the same standard I close client engagements with, the practitioner’s willingness to be paid for the verdict rather than for the verdict’s content, and if you meet one who qualifies, you have met one of the few worth the fee.
The Quick Reference Card
One section you can print, the whole method on one screen, for the reader who finished the guide and wants the working summary. Compute the life trigram from birth year and sex with the Li Chun rule, or the site’s tools. Note the group: codes 1, 3, 4, 9 are East, codes 2, 6, 7, 8 are West. Take three compass readings, resolve the sitting with the door-and-street and window-and-light tests, and identify the house trigram. Draw the floor plan’s eight sectors and mark the wandering stars from the tables in this page, house map first, personal maps for each resident. Rank the placements: door, bed, desk, stove. Allocate the dirty functions to hostile ground. Check the year’s cautions before renovating, hand dated actions to the date layer, and walk the placements quarterly, door, bed, desk, stove, five minutes, because maps drift and audits are maintenance, not events.
The four bearings summary for each code, compressed to the last useful form: Kan faces southeast, east, south, north. Zhen faces south, north, southeast, east. Xun faces north, south, east, southeast. Li faces east, northwest, southwest, south. Qian faces northeast, west, southwest, northwest. Dui faces northwest, southeast, northeast, west. Gen faces southwest, northeast, northwest, west. Kun faces northeast, west, northwest, southwest. Those are the personal Sheng Qi, Tian Yi, Yan Nian and Fu Wei bearings in order, and the hostile four are the complement, and the full tables with the reasoning sit earlier in this page for anyone who wants the working shown.
The Chinese Tradition and the Western Reader
Eight Mansions has crossed into the English-speaking world twice, once as the feng shui wave of the late twentieth century, which simplified it into lucky directions and sold it as lifestyle, and once now, as the diaspora’s practitioners write the full method in working languages, which is the wave this site is part of. The Western reader’s honest questions deserve the honest answers I give in class. The school is not religious, and it carries no belief requirement, only birth data and a compass. It is not science in the laboratory sense, and I never claim it is; it is a decision system with a three-thousand-year observation base, and its claims are testable at the level of outcomes, which this page has shown you how to test. And it is not closed: the tradition extended itself to apartment towers, induction hobs and home offices in one generation, which is the behavior of a living craft, not a museum exhibit.
The tradition also gains something in translation, which native speakers rarely admit: the English reader arrives without the folk vocabulary, the fear layer, the year-god ceremonies, and so receives the method without its accumulated superstition, the way the school’s classical authors actually wrote it, surveyor’s arithmetic for a household’s allocation. That is the version I practice and teach, and it is why the English guides on this site sometimes read cleaner than the inherited Chinese ones, a sentence I mean as respect to both languages, because the cleaning is the tradition doing what surviving traditions do, keeping the arithmetic and auditing the incense.
Final Notes From the Practice
Three closing notes, the kind I give students in the last hour of a course. First, the method is smaller than your life: the map informs the household, and the household outranks the map, and the placement that serves the family you actually are beats the placement that serves the diagram. Second, check everything, including this page: the arithmetic is here precisely so you can verify it, the anchors are published, the tables are stated cleanly, and the reader who recomputes one life trigram and one house trigram owns the method in a way the reader who believes it never will. Third, keep the instrument discipline: this school answers where, the timing systems answer when, the person’s chart answers who, and the practitioner’s maturity is measured by which instrument stays in the cabinet on any given question.
The guide is complete, and it stays free, permanently. The library section carries the next layers for readers continuing the stack, the consultation page carries the audit for buildings whose questions outrun a page, and the updates to this reference will live here as the teaching develops. You arrived with a compass question, probably one lucky direction or one hostile room, and you leave with the whole school, tables, traps, case files and boundaries included, which was the point of building the page this long. Use it well, check it often, and give the rooms you live in the ten minutes of attention they have been waiting for.
The Eight Directions, Sector by Sector
A reference readers keep asking for: the eight compass directions read as sectors of a house, independent of your personal code, the way the tradition’s surveyors described them and the way you will talk about them with any practitioner. These are the house-level readings, the qualities each direction carries in the classical literature, and the uses the tradition assigns them when a building’s layout lets you choose.
North, Kan, water. The quiet sector, associated with stillness, depth and career movement in the classical vocabulary, with water features and the flow of opportunity. Practical readings: the north sector tolerates quiet functions well, study, sleep, plumbing, and it is the one sector where the tradition both likes water and warns about excess, dampness being a form-school concern this school respects. A dark or neglected north is a common finding in audits, and the fix is light and use, in that order.
Northeast, Gen, earth. The mountain sector, stillness, the youngest-child energy, self-cultivation and the ending of cycles. Practical readings: Gen ground suits consolidation functions, storage done properly, study, meditation, and the tradition reads a dirty or cluttered northeast as a stagnation signal, which is the observation that survives translation best: the sector of stillness is the sector where clutter does its worst.
East, Zhen, wood. The thunder sector, movement, initiative, the eldest-son energy, new starts. Practical readings: east ground suits active functions, morning rooms, children’s play, exercise, and the family’s first hours, and it is the sector where stale air and blocked windows read worst, because the tradition expects movement there.
Southeast, Xun, wood. The wind sector, communication, gentle growth, the eldest-daughter energy, wealth accumulation in the classical corpus, which is why the southeast corner of the house is the famous wealth corner of popular feng shui, and the honest version is this: Xun ground rewards regular use and light circulation, and the wealth-corner industry is what happens when that single sentence gets ornamented into a figurine economy.
South, Li, fire. The fire sector, visibility, recognition, the middle-daughter energy, the sector of the home’s public face. Practical readings: south ground suits living rooms, halls, display, the family’s public hours, and it is the sector where the tradition warns against water excess, a bathroom in the south being the classic finding, managed by the containment rules rather than by plumbing surgery.
Southwest, Kun, earth. The earth-mother sector, relationships, the household’s relational ground, the marriage corner of the popular vocabulary. Practical readings: southwest ground suits shared rooms, dining, the master functions, and it is the sector where the tradition reads absence hardest, a missing southwest corner, a dead southwest room, as a relational signal, and the audit advice is use: give that ground a real room with real hours in it.
West, Dui, metal. The lake sector, joy, speech, the youngest-daughter energy, children and pleasure. Practical readings: west ground suits conversation functions, family tables, children’s rooms, entertainment, and the sector reads worst when it hosts the household’s arguments, which is to say when the room’s use contradicts the sector’s vocabulary.
Northwest, Qian, metal. The heaven sector, authority, the father energy, the household’s head and its helpful-people associations. Practical readings: northwest ground suits the study, the principal’s room, the household’s command functions, and the tradition reads a toilet or furnace in the northwest as the classic structural finding, the house’s authority ground spent on extraction, managed where the plumbing insists by the containment logic and the sector’s dignity kept by use everywhere else.
How to Use This Reference With the Star Tables
The direction reference and the wandering star tables are two halves of one reading, and the connection is the sentence I leave students with: the direction tells you what a sector wants, the star tells you what it does for you, and the placement is the intersection. A southeast sector in your building is wealth-vocabulary ground whatever your code says, but for a Kan person it is Sheng Qi, the best star, while for a Dui person it is Huo Hai, quarrel ground, so the same physical corner rewards one household’s library and punishes another’s home office, and both readings are in the tables you already have. The tradition’s surveyors worked exactly this way, direction vocabulary for the building’s character, star arithmetic for the occupants’ fit, and the modern practitioner who keeps the two halves separate from each other, the corner-is-wealth articles on one shelf and the personal-direction calculators on the other, is teaching the tradition sawn in half.
For the reader assembling the complete stack, this reference also connects to the deeper systems on this site: the trigram guide covers each of these eight characters in QMDJ terms, the five element guides cover the cycle mechanics, and the Lo Shu and flying star materials add the time dimension that this static reference deliberately leaves out. The library section links all of it, and the reading order section gives the sequence.
Common Objections, Answered Once Each
Every long teaching page earns its objections section, and here are the four I hear most, answered the way I answer them in class. “Millions of people share a birth year, so the life trigram cannot describe individuals.” Correct, and it does not try: the life trigram is not a personality model, it is a compatibility code between one person and eight directions, and the reason it survives the sharing objection is the same reason blood types survive it, the code is coarse by design and the reading is sector-level, never person-level. “The school contradicts Flying Star, so at least one is wrong.” They answer different questions with different clocks, and the comparative section shows the division of labour; contradictions between instruments mean one is being read outside its scope, which is a reading error, not a tradition failure. “Feng shui results are confirmation bias.” Some are, which is why this page hands you the checking protocol, the ninety-day observation brief and the attribution discipline; the method that survives your checking has earned its place whatever the placebo accounting says, and the one that needs your belief to work was furniture. “Why free, if it works?” Because the method’s classical authors priced it for households that could not afford surveyors, because this site’s business is the deeper stack and the audit engagements, and because a complete reference that outranks the listicles is worth more to this practice than any ebook funnel, a strategy I explain without embarrassment since it is the same strategy I used in recruitment, publish the knowledge, earn the client.
One Full Audit, Raw Data to Finished Report
The complete walkthrough, compressed to the skeleton, so you can watch every rule from this page execute in one place, then publish nothing until you have checked the arithmetic against the tables. The client: a woman, born 8 February 1978, after that year’s Li Chun, so 1978 is her feng shui birth year; female; digit sum of 1978 is 25, 2 plus 5 is 7, 5 plus 7 is 12, 1 plus 2 is 3, life trigram 3, Zhen, East group. Her bearings: Sheng Qi south, Tian Yi north, Yan Nian southeast, Fu Wei east. The building: a ninth-floor unit, main door north on a corridor, dominant windows and balcony south over the river view, so the unit faces south and sits north, a Kan house, also East group, and the house map puts its own Sheng Qi southeast, Tian Yi east, Yan Nian south, Fu Wei north.
The reading, all three stages in one paragraph each, and this is the actual deliverable shape. House level: the entrance sits on the house’s Fu Wei ground, stable and acceptable; the kitchen sits northwest, the house’s Wu Gui, containment by accident, which the report notes approvingly; the living room spreads the whole south face, the house’s Yan Nian ground, the unit’s best feature, relationship ground carrying the family’s shared hours. Person level: her bedroom sits in the unit’s east sector, the house’s Tian Yi, and the bed head pointed west, her Liu Sha bearing, the finding that mattered; the report rotates the bed head to her Yan Nian bearing, southeast, which also happens to be the house’s Sheng Qi ground, a double-support placement, and her desk, a corner of the bedroom, moves two metres to the south wall, onto the living room’s Yan Nian face, facing her Sheng Qi south over the river. Compatibility: East person, East house, structural agreement, so the report’s verdict paragraph is short, and the recommendations list is two moves and no purchases. The report closes with the ninety-day protocol and the boundaries, the whole engagement is three pages, and the client, like most clients in the good case, wrote back that the room finally felt like hers, which is the sentence the method has been producing, in one language or another, for three thousand years.
Notes From Teaching This School
Some observations from the classroom, offered because students of this page will hit the same walls my in-person students hit, and a map of the walls saves a season of confusion. The first wall is table dependence: students who memorise the star tables without the element cycles cannot debug their own charts, and the fix is to compute three stars from the cycles directly, on paper, until the table becomes a convenience instead of an oracle. The second wall is compass anxiety: students take one reading, distrust it, take another by the window frame, and panic at the disagreement, and the fix is the procedure, three interior readings, one exterior if possible, outliers discarded, confidence stated. The third wall is boundary-case paralysis: a sitting at 22.4 degrees versus 22.6, and the fix is the professional one, state both readings, note which placements differ, and let the building’s form break the tie, because a method that pretends certainty at the boundary is lying about the instrument, and compasses, like every instrument I have used in thirty years of business, have error bars.
The fourth wall is the one that separates hobbyists from practitioners, and it is not technical at all: it is the willingness to say “this placement did nothing”, out loud, in the follow-up. Students who cannot say it become the confirmation-bias machines the skeptics correctly describe, and students who can say it start building the honest ledger that the whole practice runs on. I teach the sentence in week one, and I ask students to use it in every follow-up conversation for a year, because the practitioner’s reputation compounds on the misses handled honestly, and every business I have ever run worked exactly the same way.
Sources, Thanks and the Page’s Standing
A closing note on sources and standing. The classical materials behind this page are the Ba Zhai corpus and the wider trigram literature summarized in the history section, and the modern teaching layer, the apartment conventions, the commercial applications, the calibration notes, is this practice’s own, developed across audits in Singapore, Malaysia and online, and offered here the way the classical authors offered theirs, method shown, work checkable. My students contributed a decade of questions that sharpened every section, several of the case files are composites of their buildings as much as my audits, and the page is better for the sharpening. Errors that remain are mine, and the standing offer of this site applies to this page as to all of them: find one, write in, and it gets corrected with credit, because a reference that cannot be corrected is not a reference, it is a monument, and this tradition has quite enough monuments already.
The page will be updated as the teaching develops, new case files, new building types, the occasional table clarification, and the version you are reading is the current one, maintained rather than abandoned, which is the difference between a reference and a listicle. The library section below links the deeper layers for continuation, the consultation section explains what a professional engagement adds when a building needs more than a page, and the rest of this site carries the full stack this school belongs to. Thank you for reading it this far, and for the ten minutes of attention your own rooms are about to receive, which was always the point.
The Geomancy Library: Companion Pillars
This page is one pillar in a larger lattice. The method reads deeper beside its companions: Flying Star Feng Shui, Xuan Kong Feng Shui and BaZi: Four Pillars of Destiny.
The Complete Eight Mansions Library
Beyond this pillar page, I have built a full library of 530 individual articles under the Eight Mansions method. Each one takes a specific topic, a specific room, a specific life trigram, or a specific question and answers it in practical terms. You will find dedicated guides for every life trigram (Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui), every room in the home, every best and worst sector, apartment and HDB applications, condos, corner units, facing directions, and dozens of situation-specific articles. Browse the complete Eight Mansions Library here.
Each pillar is free, complete and cross-linked, because the tradition teaches best in daylight.
