《周礼·地官司徒·司市&掌节》
胥各自掌管所治理的二肆的事务，拿着鞭杖巡视在肆门前，掌管肆中有关坐起、出入的禁令，掩捕那些违犯禁令的入。
胥各掌其所治之政，执鞭度而巡其前，掌其坐作出入之禁令，袭其不正者。
The clerks are each in charge of the affairs of the two shops they manage. They patrol in front of the shop entrance with a whip in their hands. They are in charge of the prohibition of sitting and entering the shop, and arresting those who violate the prohibition.
