《金史·列传·卷四十七》
比较起来，凡战多败，不是由于兵少，正以其多而不分健懦，因此被敌人所利用，两军对阵懦者先逃，健者不能独战就散乱，这是战败的原因。
比者凡战多败，非由兵少，正以其多而不分健懦，故为敌所乘，懦者先奔，健者不能独战而遂溃，此所以取败也。
Comparatively speaking, the reason why there are more defeats than victories in battles is not because of the shortage of soldiers, but because of the lack of classification between the strong and the weak, thus being exploited by the enemy. When two armies face each other, the weak ones flee first, and the strong ones cannot fight alone, so they become disorganized. This is the reason for the defeat.
