《庄子·杂篇·徐无鬼》
我因此泣不成声。 没过多久派遣梱到燕国去，强盗在半道上劫持了他，想要保全其身形而卖掉实在担心他跑掉，不如截断他的脚容易卖掉些，于是截断他的脚卖到齐国，正好齐国的富人渠公买了去给自己看守街门，仍能够一辈子吃肉而终了一生。齧缺遇见许由，说： 你要去哪里呢？ 
于是乎刖而鬻之于齐，适当渠公之街，然身食肉而终。啮缺遇许由曰： 子将奚之？ 
So I started to cry and could not stop. Not long after, I sent Kun to Yan Country. He was robbed by bandits on his way. The bandits wanted to keep his body intact and sell him, but he was worried he might escape, so they cut off his feet to make him easier to sell. They then went to Qi Country to sell him, where he was bought by a rich man named Qu Gong, who had him guard his front gate. He was able to eat meat for life and live out his days. Ge Que met Xu You and asked, "Where are you going?"
