《吕氏春秋·览·先识览》
中山五次割让土地给赵国，齐滑王率领全部军队在济水一带抵御以燕国为首的五国军队，都没有什么益处，都没有逃脱国亡身死的下场。
夫五割而与赵，悉起而距军乎济上，未有益也。
Zhongshan surrendered land to the state of Zhao five times, and King Huai of Qi, at the head of all his army, defended the area around the Ji River against the troops of the five states led by the state of Yan, but there was no benefit from either of these attempts, each of which merely hastened the destruction of their country.
