《后汉书·列传·吴延史卢赵列传》
到冬末行刑，毋丘长哭着对他母亲说 ：辜负了母亲，罪该死，应该怎样报答吴君呢？ 于是咬了一个指头吞吃了，含血说： 妻若生子，取名 吴生 ，说我临死吞指为誓，嘱咐儿子报答吴君。 自缢而死。
至冬尽行刑，长泣谓母曰： 负母应死，当何以报吴君乎？ 乃啮指而吞之，含血言曰： 妻若生子，名之 吴生 ，言我临死吞指为誓，属儿以报吴君。 因投缳而死。
When the execution was carried out in late winter, Wuchiu Chang cried and said to his mother: I have let you down, and I deserve to die. How should I repay Lord Wu? Then he bit off one of his fingers and swallowed it, and said with blood in his mouth: If my wife gives birth to a son, name him Wu Sheng, and tell him that I died after swallowing a finger as an oath, and to ask my son to repay Lord Wu. He then hanged himself to death.
