《魏书·列传·卷二十三》
后来确知朝廷的军队有声无实，依仗他行动在先，必定欣然前进，直达黄河，大肆杀掠，那么我方守将无法抵御。
后审知官军有声无实，恃其先聚，必喜而前行，径来至河，肆其侵暴，则我守将无以御之。
Later, it was confirmed that the imperial army was all show and no substance, and he relied on taking the lead to action. Therefore, he would be delighted to advance straight into the Yellow River and kill people on a large scale. In that case, our generals would have no way to resist.
