How to Locate Zhi Fu and Zhi Shi Step by Step

The Two Anchors of Every Qimen Chart

Every Qimen hour chart has two anchors that hold the entire structure in place. They are called Zhi Fu (直符) and Zhi Shi (直使). If you get these two wrong, every door, star, and god in your chart will sit in the wrong palace. If you get them right, the rest of the chart unfolds mechanically from there.

Despite their importance, many students skip the theory and rely on software to place them. That works until it does not. When a chart feels wrong, the first thing to check is whether Zhi Fu and Zhi Shi landed in the right palace. This article walks you through the process step by step so you can verify it yourself.

This is part of the complete guide to casting a Qimen hour chart. If you are still learning the structure selection (Yang Dun vs Yin Dun), read that guide first.

What Are Zhi Fu and Zhi Shi?

Zhi Fu (直符) means “Direct Symbol” or “Lead Star.” It is the Nine Star that sits at the head of the chart for that specific hour and structure. Its palace determines where the Heaven Plate energy is concentrated.

Zhi Shi (直使) means “Direct Envoy” or “Lead Door.” It is the Eight Door that carries the active energy for that hour. Its palace determines the direction the chart’s energy is flowing.

Together, these two define the chart’s center of gravity. Zhi Fu tells you where the heavenly energy is anchored. Zhi Shi tells you where the earthly action is directed. The relationship between them, and the palaces they occupy, forms the backbone of the interpretation.

Prerequisite: The Structure Number

Before you can locate Zhi Fu and Zhi Shi, you need the structure number for the date. This comes from the Yang Dun or Yin Dun selection and the specific pentad the date falls in. If you have not done this step, see the casting guide for the full framework.

For this article, we will assume you already have:

• The correct true solar time for the hour (see the companion article on true solar time).
• The correct Dun (Yang or Yin) and structure number.
• The hour stem and hour branch for the moment of the question.

Step 1: Identify the Hour Stem

The hour stem is the Heavenly Stem that corresponds to the Earthly Branch of the hour. Each of the 12 Earthly Branches pairs with a specific Heavenly Stem on a rotating basis. The 10 Heavenly Stems cycle through the 12 branches, creating a 60-unit cycle (the sexagenary cycle, liushijiazi).

For example, if the hour is Wu (11am to 1pm) and the specific hour pillar is Bing Wu, the hour stem is Bing. If the hour pillar is Ji Wei, the hour stem is Ji. You can find the hour pillar from a standard Chinese calendar or QMDJ calculator.

Step 2: Find Which Stem is “Hiding” Jia

In QMDJ, the stem Jia (甲) does not appear directly in the Heaven Plate. Instead, it is hidden behind one of the other nine stems. The stem that is hiding Jia for that specific hour is the one that determines Zhi Fu.

The hiding pattern follows the six Jia (六甲) system. There are six pairs, each led by a Jia stem paired with a specific hiding stem:

To find the hiding stem, determine which of the six Jia units the hour pillar falls in. Each Jia unit covers 10 pillars in the 60-unit cycle. Once you know the Jia unit, look up the hiding stem from the table above.

Step 3: Place Zhi Fu in the Heaven Plate

Now you have the hiding stem. The next step is to find which palace that stem sits in for this specific structure number.

The Heaven Plate distributes the 10 stems (9 visible, 1 hidden) across the 9 palaces according to the structure number. The structure number determines which palace the lead stem (Wu, the hiding stem for Jia Zi) starts in. From there, the other stems follow in the Luoshu sequence.

The process:

1. Find the palace where the structure number places the lead stem (Wu for Yang Dun, or the counterpart for Yin Dun).
2. Follow the stem rotation to find where your hiding stem sits.
3. That palace is where Zhi Fu (the lead star) sits.

The Nine Star that corresponds to that palace becomes the Zhi Fu. Each palace has a fixed star assignment, so once you know the palace, you know the star.

Step 4: Place Zhi Shi in the Earth Plate

Zhi Shi follows from Zhi Fu. Once you have Zhi Fu’s palace, Zhi Shi sits in the same palace number but on the Earth Plate (the door layer). The door that corresponds to that palace is the Zhi Shi.

The key relationship: Zhi Fu and Zhi Shi always start in the same palace. They diverge when you apply the rotation rules for the Eight Doors and Nine Stars, but the starting point is shared.

Zhi Fu and Zhi Shi are born in the same palace. They separate the moment the chart starts to move. The star looks up. The door looks out. Together they tell you where the energy is and where it wants to go.

Step 5: Rotate the Stars and Doors

From the starting palace, the remaining stars and doors rotate according to the Dun direction:

• Yang Dun: stars and doors rotate forward through the palaces (1 to 9).
• Yin Dun: stars and doors rotate in reverse (9 to 1).

The Eight Doors follow the same rotation direction as the Nine Stars, but they follow a different palace sequence because there are only 8 doors (not 9). The door that is not assigned to the central palace stays in place while the others rotate.

For a complete guide to the rotation rules, see the companion article on rotation rules for doors, stars, and gods and the Eight Doors complete guide.

Verifying Your Placement

After placing Zhi Fu and Zhi Shi, do a quick verification:

• Check the palace consistency: Zhi Fu and Zhi Shi should start in the same palace. If they are in different palaces, something went wrong in the stem lookup.
• Check the rotation direction: Yang Dun should have forward rotation. Yin Dun should have reverse. If the other stems in the chart do not follow this direction, the structure number or the Dun may be wrong.
• Check against the hour stem: The hiding stem you identified should match the hour pillar. If the hour pillar is Jia Zi, the hiding stem must be Wu. If it is Jia Xu, the hiding stem must be Yi. A mismatch here means the hour stem was incorrectly identified.

Common Mistakes and How to Avoid Them

Forgetting the six Jia system

Many beginners try to look for Jia directly in the chart and get confused when it is not there. Jia is always hidden. You must use the six Jia lookup to find which stem is carrying it for that hour.

Using the wrong stem cycle

The Heavenly Stems cycle in a specific order: Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, Gui. If you mix up the order, the hiding stem will be wrong and the entire chart shifts. Memorize the sequence or keep a reference card handy.

Confusing Zhi Fu the star with Zhi Fu the stem

In QMDJ terminology, Zhi Fu can refer to both the hiding stem and the lead star. They are related but not identical. The hiding stem tells you which stem to look for. The palace that stem sits in determines which star is the lead star (also called Zhi Fu). The star takes its name from the palace, not from the stem.

Frequently Asked Questions

Why does Jia hide behind other stems?

In classical QMDJ theory, Jia (甲) represents the supreme commander. It is too important to be exposed directly, so it hides behind one of the other nine stems. The art is called Dun Jia, literally “hiding Jia.” This is not a metaphor. It is the core mechanic of the chart’s stem placement.

Can Zhi Fu and Zhi Shi be in different palaces?

They start in the same palace, but after rotation they can move to different positions depending on the structure. However, the starting palace is always the same. If the starting palaces differ, there is an error in the calculation.

Do I need to memorize the six Jia pairings?

For accuracy and speed, yes. The six pairings (Jia Zi to Wu, Jia Xu to Yi, Jia Shen to Geng, Jia Wu to Xin, Jia Chen to Ji, Jia Yin to Gui) are used in every single chart. Once memorized, locating Zhi Fu becomes a quick lookup rather than a multi-step calculation.

What happens if software places Zhi Fu differently than my manual calculation?

Double check the true solar time and the structure number first. If those match, check whether the software uses the same six Jia system. Some modern variants use a slightly different hiding convention, but the classical system described here is the standard for QMDJ hour charts.

Key Takeaways

• Zhi Fu (lead star) and Zhi Shi (lead door) are the two anchors of every hour chart.
• Both start in the same palace, determined by the hiding stem for Jia and the structure number.
• The six Jia system pairs each Jia unit with a specific hiding stem. You must look up the correct pair for your hour pillar.
• Yang Dun rotates forward, Yin Dun rotates in reverse. Getting the direction wrong shifts the entire chart.
• Always verify: same starting palace for Zhi Fu and Zhi Shi, correct rotation direction, matching hiding stem.

Once Zhi Fu and Zhi Shi are correctly placed, the rest of the chart, including the Eight Doors, the Nine Stars, and the Eight Gods, flows mechanically from the rotation rules. The anchors hold the chart in place. Get them right and interpretation becomes the focus, not the mechanics.
