Xin Wei (辛未) Jiazi Pair Explained: The 8th of 60 Combinations

The Xin Wei Pair (辛未): Jiazi Explained

Xin Wei (辛未) is the 8th of the sixty Jiazi pairs, the stem-branch combinations that structure the entire Chinese calendar, BaZi charts and Qi Men Dun Jia timing alike. In the current cycle its years are 1991 and 1990, followed by its partner pair Geng Wu (庚午) completing the same nayin group.

If that sounds abstract, think of the sixty pairs as the alphabet of Chinese time. Every year, month, day and hour in these systems is written in one of these sixty combinations, so understanding a pair is understanding the vocabulary the whole system speaks.

Xin Wei Quick Facts

What the Xin Wei Pair Means: A Nourishing Pair

Classical analysis of a stem-branch pair starts with their elements, and here the branch feeds the stem: Earth generates Metal. The ground nourishes the core, which classically reads as a supported, well-fed pairing where circumstances feed the person’s own energy rather than fight it.

This relation is why two pairs can both be called auspicious while feeling completely different in a life. The nourishing pairs suggest support arriving from the environment; the commanding pairs suggest the person taking charge of the environment; the disciplining pairs suggest life itself as the teacher. None of the five relations is good or bad. Each is a style of exchange between a person’s core and their ground.

The Two Years of the Earth by the Roadside Nayin Group

Xin Wei (辛未) and Geng Wu (庚午) share the nayin Earth by the Roadside (路旁土): soil that supports everyone passing by: humble, service-oriented, patient. People born in 1991 carry the Metal Goat year, and people born in 1990 carry the Metal Horse year. The year-by-year detail, including the Li Chun boundary and the branch interactions, lives on the dedicated year pages, and the full chart method is in the BaZi chart guide.

Year-by-year readings for this pair: BaZi 1990, BaZi 1991.

Because the cycle repeats every sixty years, Xin Wei years also include 1931, 1871, and will return in 2051. The pair is the same; the generations differ, which is a nice reminder that a chart describes energies, not destinities.

Where Jiazi Pairs Appear in Your Chart

Every pillar in your BaZi is a jiazi pair: year, month, day and hour each carry one of these sixty combinations. The day pillar, most important of the four, has a one-in-sixty chance of being Xin Wei, and practitioners meet the pair again in decade luck cycles, annual years and QMDJ charts. If you want to see how the pairs are actually extracted from birth data, the beginner step-by-step guide walks through the whole process in one sitting.

The Goat Branch in Xin Wei

The branch carries the zodiac identity of the pair, here the Goat, and with it the layer people actually feel in daily life. Every Goat year, month, day or hour written with this branch carries the same family of themes: the tendencies, the strengths and the friction points that follow the Goat wherever the pair appears in a chart. Readers who want the full Goat picture, from branch interactions to 2027 timing, will find it in the zodiac and BaZi references on this site.

How to Find Your Own Jiazi Pair

Any BaZi chart lists the four pillars, and each pillar is one of these sixty pairs. Look up the day pillar, which most software and printed charts mark clearly, and the pair name written beside it is the one to study first. The year pillar pair, like the one this page describes when you were born in 1991, is the background layer; the day pair is the core. Both are worth knowing, and both take under a minute to find with the beginner plotting guide.
