王答道： 从前齐桓公知道郭公灭亡的原因，在于喜好良言而不能采用，而桓公本人弃置进良言的人，管仲认为这与郭公没什么两样。
对曰： 昔齐桓公知郭公之所以亡，由善善而不能用，然弃其所言之人，管仲以为无异于郭公。
Wang replied: In the past, Qi Huangong understood the reason why Guo Gong was destroyed. He liked hearing good words but would not use them. And Huangong himself abandoned those who offered good advice. Guan Zhong thought that this was no different from Guo Gong.
