《汉书·志·五行志中之上》
定公十五年 正月，鼷鼠啃食祭祀用牛，牛死 。刘向认为，鲁定公知道季氏驱逐了鲁昭公，罪恶昭彰，所以亲自参加夹谷之会用孔子辅佐。会上孔子制服齐国，齐人归还了郸、谁、龟阴的土地。圣德这么大，返回后却用季桓子执政，沉湎于女乐歌舞，辞退了孔子。这太失为君之道了。《诗经》上说： 人如果抛弃了礼仪，还活着干什么！ 
刘向以为，定公知季氏逐昭公，罪恶如彼，亲用孔子为夹谷之会，齐人俫归郓、讠雚、龟阴之田，圣德如此，反用季桓子，淫于女乐，而退孔子，无道甚矣。《诗》曰： 人而亡仪，不死何为！ 
In the 15th year of Dinggong, in the first month of the lunar calendar, shrew mice gnawed at the cattle used for sacrifices, and the cattle died. Liu Xiang believed that Duke Ding of Lu knew that Ji Shi had expelled Duke Zhao of Lu. The crime was obvious, so he participated in the Jia Gu meeting in person with Confucius as his assistant. At the meeting, Confucius conquered Qi, and the Qi people returned the land of Dan, Sui and Guiyin. The sacred virtue was so great, but after returning, he let Ji Huanzi take charge of the government, indulged in singing and dancing of women, and dismissed Confucius. This is too unworthy of the way of a monarch. The Book of Songs says: If a person abandons etiquette, what good is it to live!
