《容斋随笔·卷六·孔子欲讨齐》
对此事，《左传》的记载是： 孔子请求讨伐齐国，鲁哀公说： 鲁国比齐国弱已是很久的事实了。你说要讨伐他，结果会怎么样呢？ 
《左传》曰： 孔子请伐齐，公曰： 鲁为齐弱久矣，子之伐之，将若之何？ 
Regarding this matter, Zuo Zhuan records that Confucius asked to attack the state of Qi, and Lu Aihou said: It is a long-established fact that the state of Lu is weaker than the state of Qi. What will happen if you say you want to attack him?
