《左传·哀公·哀公十五年》
吴国人把动乱加于敝邑，齐国乘敝邑的困难，占取了瓘地和阐地，寡君因此而寒心，如果能像卫君那样事奉贵君，那本来就是我们所希望的。 
吴人加敝邑以乱。齐因其病，取讙与阐。寡君是以寒心。若得视卫君之事君也，则固所愿也。 
Wu inflicted chaos upon our humble state, and Qi took advantage of our difficulties and occupied Guandi and Chundi. Our ruler is disheartened by this. If we could serve your ruler like Wei does, it would be what we have always wished for.
