《资治通鉴·梁纪·梁纪十二》
北魏孝武帝责难高欢说道： 纥豆陵伊利既没有入侵，也没有叛变，是我们魏国忠贞的臣子，您突然讨伐他，难道有一个使者事先来请示过吗？ 
魏主让之曰： 伊利不侵不叛，为国纯臣。王忽伐之，讵有一介行人先请之乎！ 
Emperor Xiao Wu of Northern Wei accused Gao Huan and said: Ge Douling Yili had neither invaded nor revolted, he was a loyal subject of the Wei kingdom, why did you attack him without sending a messenger to ask for my opinion first?
