《吕氏春秋·览·审应览》
官吏回答说： 宓子让我们书写，却不时地摇动我们的胳膊肘，写得不好又大发脾气，堂父的官吏都因宓子这样做而发笑。
吏对曰： 宓子使臣书，而时掣摇臣之肘，书恶而有甚怒，吏皆笑宓子。
The officials replied: "Mi Zi asked us to write, but he would shake our elbows from time to time. If we wrote poorly, he would be very angry. The officials of Tangfu all laughed because Mi Zi did this."
