《资治通鉴·隋纪·隋纪八》
屈突通的处境愈加窘迫。有人劝屈突通投降，屈突通哭道： 我侍奉过两个主上，皇帝对我的恩宠照顾非常优厚，拿着人家的俸禄而在困难时背叛，我不能做这样的事！ 
或说通降，通泣曰： 吾历事两主，恩顾甚厚。食人之禄而违其难，吾不为也！ 
Qututong's situation became increasingly difficult. Some people persuaded Qututong to surrender, and Qututong cried: I have served two rulers, and the emperor treated me with the utmost kindness and consideration. I cannot do something like betray someone who has given me a position at a time of difficulty!
