《管子·任法》
大臣喜爱某人，就替他进行私赏；大臣憎恶某人，就替他进行私罚；违背公法，丧失正心，一味听大臣摆布的，是危产的君主。
臣有所爱而为私赏之，有所恶而为私罚之，倍其公法，损其正心，专听其大臣者，危主也。
If the minister loves someone, he will reward him privately; if the minister hates someone, he will punish him privately; if he violates the public law, loses his heart, and listens to the minister's words, he will be a monarch in danger.
