"What are Yi people like" is a high-frequency search whose answers are almost all borrowed adjectives. This page goes the other way: everything computable about Yi (Yin Wood) is computed here — where Lu, the blade, the noblemen and Wenchang land, which stem it combines with and into what, which stem clashes it, its six of the sixty day pillars, and the twelve-stage strength of every branch. Every number is checkable and every rule is on the methodology page. No adjectives produced; structure you can audit.
This page is generated from engine vv0.14.0; the Lu-equals-Official-Post and blade-equals-Prosperity cross-checks are asserted for all ten stems at build time — conventions R32/R34.
| Day master | 乙 Yi · Yin Wood |
|---|---|
| Lu — the Official-Post seat | 卯 Mao — cross-checked: the Official-Post seat of Yi lands exactly here |
| Yin blade — the Prosperity seat | 寅 Yin — the yin blade is one school's reading; another school gives yin stems no blade at all — divergence kept public |
| Nobleman branches (both schools) | Zi and Shen (main) (the alt school agrees) |
| Wenchang — the study star | 午 Wu |
| Stem combine (and what it becomes) | Yi combines with Geng; the pair transforms to Metal |
| Stem clash | Xin — one of the four heavenly clashes |
| Twelve-stage start | Birth begins at 午 Wu, counting backward (Yin stems) |
| Day pillars carrying this stem | 6 of 60: 乙丑 Yi Chou, 乙亥 Yi Hai, 乙酉 Yi You, 乙未 Yi Wei, 乙巳 Yi Si, 乙卯 Yi Mao |
| Prosperity inside its own pillars | none of the sixty day pillars puts Yi on its Prosperity branch (parity of stems and branches blocks it — see the index distribution) |
One row per branch: main-qi hidden stem, ten god against the day master, its twelve-stage strength, and where Lu, the blade, the noblemen and Wenchang land. Blanks in the marks column are information too.

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.
