《资治通鉴·唐纪·唐纪十五》
如今没有这三条原因而只是无故烦劳中原百姓，我们对内无非称为前代雪耻，对外不过称为新罗报仇，岂不是所得到的很少，失去的很大吗！
今无此三条而坐烦中国，内为前代雪耻，外为新罗报仇，岂非所存者小，所损者太乎！
Now that there are no such three reasons, but only for no reason to bother the common people of the Central Plains, we can only call it a shame for the previous generation, and externally it can only be called revenge for Silla. Isn't it too little to gain and too much to lose?
