《资治通鉴·唐纪·唐纪五十四》
李绛说： 这一类人大都不懂得仁义，分不清是非，唯利是图，只要是得到贿赂，就能将盗跖、庄赞誉成廉洁善良之人；如果违背了他们的意志，便可将龚遂、黄霸毁谤为贪婪暴虐的，能够使用狡诈的智虑，捏造成是非难辨的事端，时时刻刻围绕在四周，将谗言逐渐渗透进去，陛下肯定有时候也会相信他们的。
就使为之，朕亦不听。 绛曰： 此属大抵不知仁义，不分枉直，唯利是嗜，得赂则誉跖、足乔为廉良，怫意则毁龚、黄为贪暴，能用倾巧之智，构成疑似之端，朝夕左右浸润以入之，陛下必有时而信之矣。
Li Jiang said: Most of this kind of people do not understand benevolence and righteousness, cannot distinguish between right and wrong, and only seek profits. As long as they receive bribes, they can praise robbers and villains like Duo and Zhuang as honest and kind people; If they are against their will, they can slander Gong Sui and Huang Ba as greedy and brutal. They can use cunning strategies to create indistinguishable right and wrong, surround you at all times, and gradually infiltrate slander. Your Majesty will definitely believe them sometimes.
