《资治通鉴·周纪·周纪三》
对郭隗说： 齐国趁我国内乱而攻破燕国。我深知燕国国土狭小、国力贫弱，没有报仇的能力；然而如果真的能求得贤士一起治理政事，一雪先王的屈辱，这是我的心愿。
谓郭隗曰： 齐因孤之国乱而袭破燕，孤极知燕小力少，不足以报。然诚得贤士与共国，以雪先王之耻，孤之愿也。
Guo Wei said: The state of Qi attacked the state of Yan while my country was in turmoil. I fully understand that the state of Yan is small and poor, and has no chance of revenge. However, if I can really ask wise men to govern the country together, this is my wish to wash away the humiliation of the former king.
