金鸡独立

Earliest clear written source is Qing novelist Li Ruzhen's 《镜花缘》, chapter 74: 我是'金鸡独立'，要一足微长 ('I'll do Golden Rooster Standing on One Leg — one foot needs to be slightly raised'). The phrase became fixed as both a tai-chi posture (太极拳金鸡独立势) and a general description of one-legged standing.

In tai chi (太极拳) and xingyi (形意拳), 金鸡独立 is a named form where the practitioner stands on one leg with the other knee raised and hand extended — used for balance training and as a combat stance.
