《汉书·传·魏相丙吉传》
即使是介之推那样的割自己的肉给君主吃，以使君主存活的行为，也不能与之相比。孝宣皇帝在时，我曾上书说明当时的情状，奏书有幸到了丙吉那裹，丙吉十分谦虚，不自我炫耀，删去了我奏书中关于他的那些话，而把好处全归功于胡组和郭征卿，胡组、郭征卿都因此被赏赐给了田宅、金钱，丙吉被封为博阳侯。臣尊我不能和胡组、郭征卿相比。
教宣皇帝时，臣上书言状，幸得下吉，吉谦让不敢自伐，删去臣辞，专归美于组、徽卿。组、徽卿皆以受田宅赐钱，吉封为博阳侯，臣尊不得比组、徽卿。
Even the behavior of slashing his own flesh to feed the monarch in order to save the monarch's life, like Jie Zitui, cannot be compared with it. When Emperor Xiaoxuan was in power, I wrote a letter to explain the situation at that time. Fortunately, the book reached Bingji, who was very humble, did not show off, and deleted the words about him in my book, but attributed all the benefits to Hu Zu and Guo Zhengqing, Hu Zu and Guo Zhengqing were rewarded with land and money, and Bingji was named Boyang Hou. I think I can't compare with Hu Zu and Guo Zhengqing.
