《汉书·传·萧何曹参传》
曹亩休假回家，有空的时候，自随其意劝谏曹参，曹参生气地责打他二百下，说： 快去入朝侍奉，天下事不是你应当说的。 
窋既洗沐归，时间，自从其所谏参。参怒而笞之二百，曰： 趣入侍，天下事非乃所当言也！ 
When Cao Mu was on leave to return home, one day at his leisure, he hinted at Cao Can, Cao Can got angry and lashed him 200 times, and said: "Quickly go to court to serve, the affairs of the world are not something you should say."
