Fang Jing and Emperor Wu of the Han Dynasty discussed this issue together. Fang Jing asked Emperor Wu of Han Dynasty: Why did You Wang and Li perish? Who did they hire? Emperor Han Yuan replied: The people they appointed were unfaithful. Jing Fang said: I know they are disloyal, but I hired them. Why? Emperor Yuan of the Han Dynasty said: Kings of subjugation all thought their ministers were very talented. Knowing that they are disloyal, how can they appoint them? Jing Fang saluted Emperor Han Yuan and said, I'm afraid we look at the ancients now, just as future generations look at us now!
