Geng Wu (庚午) Jiazi Pair Explained: The 7th of 60 Combinations

The Geng Wu Pair (庚午): Jiazi Explained

Geng Wu (庚午) is the 7th 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 1990 and 1991, followed by its partner pair Xin Wei (辛未) completing the same nayin group.

Metal on a horse is a blade at full gallop. Magnificent tool, wrong hands, very bad afternoon.

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.

Geng Wu Quick Facts

What the Geng Wu Pair Means: A Disciplining Pair

Classical analysis of a stem-branch pair starts with their elements, and here the branch restrains the stem: Fire controls Metal. The ground disciplines the core, which reads as pressure that shapes: structure, restraint and lessons arriving through circumstances rather than through choice.

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

Geng Wu (庚午) and Xin Wei (辛未) share the nayin Earth by the Roadside (路旁土): soil that supports everyone passing by: humble, service-oriented, patient. People born in 1990 carry the Metal Horse year, and people born in 1991 carry the Metal Goat 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, Geng Wu years also include 1930, 1870, and will return in 2050. 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

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 Horse Branch in Geng Wu

The branch carries the zodiac identity of the pair, here the Horse, and with it the layer people actually feel in daily life. Every Horse 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 Horse wherever the pair appears in a chart. Readers who want the full Horse 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 1990, 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.
