The second Earthly Branch — late winter, frozen Earth, a Metal vault. Its zodiac animal is the Ox.
Overview
Chou (丑) is the second Earthly Branch, and the same distinction holds: Chou is the branch; the Ox is the popular Chinese-zodiac animal that corresponds to it. Chou is not 'the Ox' — it is Chou, a calendrical unit, and the Ox is its familiar label.
As a branch, Chou is the cold, damp earth of late winter — the 12th lunar month, the hours before dawn, the frozen field. Its element is Earth, but a wet, wintry Earth that holds things rather than grows them. Classically it is one of the four 'storage' branches: the vault where Metal is kept in the ground, patient and load-bearing.
As a unit of time
As a unit of time, Chou rules 01:00–03:00 (the 丑時 double-hour), the 12th lunar month at winter's end, and a north-northeast position. A chart reads it by which pillar it occupies — its placement is a coordinate in the calendar.
Hidden stems (藏干)
Chou's hidden stems (藏干) are Yin Earth (己) as its main qi, plus Yin Water (癸) and Yin Metal (辛). That mix is why Chou is more than plain Earth: it is the 'Metal storehouse', earth with refined Metal buried inside and a residue of winter Water. The hidden stems are how a branch carries several elements at once.
Clashes, trinities, combinations
Chou's clash (六沖) is with Wei (未, the Goat) — the two earthy storehouse branches on opposite sides of the year. It belongs to the Metal trinity (三合) 巳酉丑 (Si–You–Chou) as the storage member, and its six-combination (六合) is with Zi (子, the Rat), the pair combining toward Earth. These are structural ties between chart positions, not event forecasts.
Cross-system reference
| System | Closest archetype | Note |
|---|---|---|
| Zi Wei Dou Shu | One of the twelve fixed cells of a Zi Wei chart — the 丑 position a palace sits on | In Zi Wei the twelve Earthly Branches are the chart's twelve fixed cells: every palace occupies a branch, and a chart's 命宮 (Life Palace) can land on 丑. Its Bazi clash partner 未 (Goat) sits in the cell directly opposite — what Zi Wei reads as the 對宮 (opposite palace) on the same axis. Same twelve branches, used as the spatial frame for the palaces, not as a Bazi pillar. |
| Chinese zodiac (生肖) | The Ox — the popular animal label for the branch Chou | The Ox is the everyday zodiac's name for Chou, but that is the popular layer; the branch Chou — its Earth element, its hidden Metal and Water, its time and interactions — is the technical unit a Bazi chart uses. |
| Western astrology | A loose structural parallel only — twelve divisions of a cycle | No sign maps to a branch. The branches are calendrical units, not a zodiac of personality types; the only parallel is the shared twelve-fold division. |
The Chinese zodiac animal is a popular label for the branch, not the branch itself, and there is no branch-to-Western-sign mapping. Cross-system anchors are a loose heuristic; an Earthly Branch is a calendrical unit with hidden stems, which neither the zodiac nor Western astrology shares.
Reading this descriptively
Chou describes a position in time and its elemental character — late-winter storage Earth — not a personality, not a destiny, and not 'you are an Ox'. It is read against the rest of the chart, and the same branch plays out very differently across different lives.
