The sixth Earthly Branch — early summer, rising Fire with hidden Metal. Its zodiac animal is the Snake.
概覽
Si (巳) is the sixth Earthly Branch, and the distinction stands: Si is the branch; the Snake is the popular Chinese-zodiac animal that corresponds to it. Si is not 'the Snake' — it is Si, a calendrical unit, with the Snake as its familiar label.
As a branch, Si is the rising fire of early summer — the 4th lunar month, late morning, the heat beginning to build. Its element is Fire, bright and coiled like a forge, and one of the four 'growth-opening' branches that begin a season. What makes Si distinctive is the Metal hidden in its heat — the forge that will, by autumn, produce Metal.
作為時間單位
As time, Si rules 09:00–11:00 (the 巳時 double-hour), the 4th lunar month at summer's opening, and a south-southeast position. Its pillar placement fixes which layer of the chart this rising Fire colours.
藏干
Si's hidden stems (藏干) are Yang Fire (丙) as the main qi, with Yang Earth (戊) and Yang Metal (庚). The buried Metal is the surprise: this Fire branch is also where Metal is born (the 'long life' stage of Metal), so Si carries the seed of the element its heat seems to oppose. The hidden stems hold that paradox inside the branch.
六沖、三合、六合
Si's clash (六沖) is with Hai (亥, the Pig) — the Fire-against-Water, summer-against-winter axis. It opens the Metal trinity (三合) 巳酉丑 (Si–You–Chou), and its six-combination (六合) is with Shen (申, the Monkey), combining toward Water. These are structural relationships between chart positions, not predictions.

| Zi Wei Dou Shu | One of the twelve fixed cells of a Zi Wei chart — the 巳 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 巳. Its Bazi clash partner 亥 (Pig) 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. |

生肖動物只是地支的通俗別名、不是地支本身，地支與西方星座之間也沒有對應。跨系統對照只是鬆散參考；地支是帶藏干的曆法單位，這個結構生肖與西方占星都沒有。
以描述而非預言來讀
Si describes a position in time and its elemental character — early-summer rising Fire — not a personality, not a destiny, and not 'you are a Snake'. It is read against the rest of the chart, and the same branch plays out very differently across different lives.
