Branch 2 of 12 · Chou (Ox)

The Ox branch (丑) — Yin Earth, Northeast, 01:00–03:00

The Ox branch is number 2 of the twelve: yin Earth, the animal Ox, the 12th month (beginning at Minor Cold), the hour 01:00–03:00, direction Northeast, 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.

How this branch relates to the others

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.

Where the ten stems stand on this branch

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.

The five pillars containing this branch

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:

Yi Chou · Ding Chou · Ji Chou · Xin Chou · Gui Chou

A note on what this page deliberately does not do: the popular versions of this material assign a fixed personality to each term — one character per branch, one destiny per stage. This site rejects that framing. What is published here is a structural position: which element sits where, on what kind of ground, with which tenants inside. The same term reads differently under a different month command, and no meaningful judgement exists without the other characters of the chart. Where the tradition offers a reading it is labelled as the tradition's; this site's own contribution is that every number and term on this page is computed, versioned and checkable against the methodology page.

Frequently asked

What is the Ox branch?
It is number 2 of the twelve branches: yin Earth, the animal Ox, the 12th month (beginning at Minor Cold), the hour 01:00–03:00, direction Northeast. Its hidden stems are Ji + Gui + Xin.
Which hours belong to the Ox hour?
The Ox hour covers 01:00–03:00. This site treats the hour as a two-hour block and publishes both conventions for the 23:00 day change (the mainstream Zi Ping rule that rolls to the next day, and the midnight rule) — see the methodology page.
Which branches combine with or clash with Ox?
Six harmony: Zi (Rat) (combining into Earth). Clash: Wei (Goat). Harm: Wu (Horse). Trine: Si (Snake), You (Rooster), Chou (Ox). Meeting: Hai (Pig), Zi (Rat), Chou (Ox). These are fixed table relations and every one of them is checkable on this page.
Is the Ox branch good or bad?
A single branch is neither. Ox is a structural position: its element, its hidden stems and its relations to the other branches only mean something inside a whole chart. Any source that grades an individual branch as lucky or unlucky is claiming more than the system itself does.
