《吕氏春秋·纪·季冬纪》
充任使者，遭到拥有万辆兵车的威重的君主的侮辱，退下自刎，但一定用自己己的血染污对方的衣服，有如我这样的，孟尝君那里有七人。 
万乘之严主辱其使者，退而自刎也，必以其血污其衣，有如臣者七人。 
Acting as an envoy, he was insulted by a powerful monarch with tens of thousands of chariots. He retired and killed himself, but he made sure to stain the other party's clothes with his own blood. There were seven people like me in Lord Mengchang's place.
