The eleventh Earthly Branch — late autumn, dry Earth, a Fire vault. Its zodiac animal is the Dog.
Overview
Xu (戌) is the eleventh Earthly Branch, and the distinction stands: Xu is the branch; the Dog is the popular Chinese-zodiac animal that corresponds to it. Xu is not 'the Dog' — it is Xu, a calendrical unit, with the Dog as its familiar label.
As a branch, Xu is the dry earth of late autumn — the 9th lunar month, early evening, the year banking down toward winter. Its element is Earth, but a dry, guarded Earth: one of the four 'storage' branches, the vault where Fire is kept as a banked ember, holding a residue of autumn's Metal.
As a unit of time
As time, Xu rules 19:00–21:00 (the 戌時 double-hour), the 9th lunar month at autumn's close, and a west-northwest position. Its pillar placement fixes which layer of the chart this dry storage-Earth colours.
Hidden stems (藏干)
Xu's hidden stems (藏干) are Yang Earth (戊) as the main qi, with Yin Metal (辛) and Yin Fire (丁). That is why Xu is the 'Fire storehouse': dry Earth on the surface, with banked Fire and a remnant of autumn Metal buried inside. The hidden stems carry several elements at once.
Clashes, trinities, combinations
Xu's clash (六沖) is with Chen (辰, the Dragon) — the two earthy storehouse branches on opposite sides of the year. It is the storage member of the Fire trinity (三合) 寅午戌 (Yin–Wu–Xu), and its six-combination (六合) is with Mao (卯, the Rabbit), combining toward Fire. These are structural relationships between chart positions, not predictions.
Cross-system reference
| System | Closest archetype | Note |
|---|---|---|
| Zi Wei Dou Shu | One of the twelve fixed cells of a Zi Wei chart — the 戌 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 戌. Its Bazi clash partner 辰 (Dragon) 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 Dog — the popular animal label for the branch Xu | The Dog is the everyday zodiac's name for Xu; the branch Xu — its Earth element, hidden Fire and Metal, time and interactions — is the technical unit a Bazi chart reads. |
| Western astrology | A loose structural parallel only — twelve divisions of a cycle | No sign maps to a branch; the branches are calendrical, not personality signs. 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
Xu describes a position in time and its elemental character — late-autumn storage Earth — not a personality, not a destiny, and not 'you are a Dog'. It is read against the rest of the chart, and the same branch plays out very differently across different lives.
