踞坐有五事：一者不得交足、二者不得雙前兩足、三者不得却踞兩手掉捎兩足、四者不得支柱一足申一足、五者不得上下足。

Squatting has five matters: first, one must not cross one's legs; second, one must not thrust both feet forward together; third, one must not lean back, shaking both hands and legs; fourth, one must not prop up one leg while extending the other leg; fifth, one must not place one foot atop the other.
