《金史·列传·卷四十七》
他方见我来势盛大，必定坚守不出，我军匆忙而无所得，必须回军来取粮，对方乘机来袭击，将使我方要战不得，要退不能，那时休兵的日期就难以等到了。
彼见吾势大，必坚守不出，我军仓猝无得，须还以就粮，彼复乘而袭之，使我欲战不得、欲退不能，则休兵之期殆未见也。
If the other side sees that our forces are powerful, they will definitely stay behind closed doors and not come out. My army will be in a hurry and gain nothing, and we must return to get food. The other side will take the opportunity to attack, making it difficult for us to fight or retreat. At that time, it will be difficult to wait for the day of truce.
