《韩非子·安危》
君主不要求自己像尧，却要求臣下都像伍子胥，这好比希望殷人都像忠直的比干那样，都像比干那样，君主自然就不会有什么过失，臣下也就不会背离君主。
人主不自刻以尧而责人臣以子胥，是幸殷人之尽如比干；尽如比干，则上不失，下不亡。
The monarch does not ask himself to be like Yao, but he asks his ministers to be like Wu Zixu. This is like hoping that all the people of Yin would be like the loyal Bigan. If they were all like Bigan, the monarch would not have made any mistakes, and the courtiers would not have deserted the monarch.
