《论衡·卷二十六·知实篇》
梁惠王对此很不高兴，因此责备那个宾客说： 你赞扬淳于先生，说管仲、晏婴都赶不上他，等到他见了我，我并没有什么收获。
惠王怪之，以让客曰： 子之称淳于生，言管、晏不及。及见寡人，寡人未有得也。
King Hui was very unhappy about this, so he scolded the guest and said, "You praised Mr. Chunyu, saying that Guan Zhong and Yan Ying were not as good as him. When he saw me, I got nothing from him."
