《后汉书·列传·桓谭冯衍列传上》
鲍永与你冯衍，拥着符节印绶，自相署立为官，以前仲由使门人为臣，孔子讥笑其诈为欺天。
君长、敬通揭节垂组，自相署立。盖仲由使门人为臣，孔子讥其欺天。
Bao Yong and you, Feng Yan, have seized the imperial seal and ribbons, and have appointed each other as officials. In the past, Zhong You used his doorman as a minister, and Confucius ridiculed his deceit as an attempt to deceive Heaven.
