The Pig branch is number 12 of the twelve: yin Water, the animal Pig, the 10th month (beginning at Start of Winter), the hour 21:00–23:00, direction Northwest, season Winter. Below are the structural facts — hidden stems, six-harmony, clash, harm, punishment, trine and meeting — plus which of the twelve stages each of the ten stems occupies on this branch. All of it is computed and checkable; none of it is a personality verdict.
This page is generated from the engine v0.14.0, not hand-written; structural facts reconcile against the methodology page.

Branch relations are fixed tables — combination, clash, harm, punishment, trine and meeting each have a defined membership. This site computes them from those tables and does not add the popular "once combined, everything improves" clause.
| Six harmony | 寅 Yin (Tiger) — combines into Wood |
|---|---|
| Six clash | 巳 Si (Snake) |
| Six harm | 申 Shen (Monkey) |
| Punishment | Self-punishment (one of Chen, Wu, You, Hai) |
| Three harmony | Wood trine: 亥 Hai (Pig) 卯 Mao (Rabbit) 未 Wei (Goat) |
| Meeting | North Water meeting: 亥 Hai (Pig) 子 Zi (Rat) 丑 Chou (Ox) |
The twelve stages describe how strong a stem is on a given branch. Yang stems run forward, yin stems run backward, so each of the ten stems lands on exactly one stage per branch. The ten rows below are computed; the stage names link to their full definitions.

|---|---|---|
| 甲 Jia Yang Wood (yang Wood) | Birth | 1 of 12 |
| 乙 Yi Yin Wood (yin Wood) | Death | 8 of 12 |

Each branch appears in five of the sixty pillars (a yang branch only pairs with yang stems, a yin branch only with yin stems). Every pillar has its own page:
Every enumerable component of ba zi has its own page here. Each page is computed by the same engine and can be checked item by item — none of it is a personality table.
