《资治通鉴·梁纪·梁纪十七》
现在，如果派出少量人马，不能攻破贼兵，只会白白挫伤自己的锐气；如果派出的人马很多，一旦失利，城门狭窄、浮桥又小，一定会导致重大伤亡！ 
今出人若少，不足破贼，徒挫锐气；若多，则一旦失利，门隘桥小，必大致失亡。 
Right now, if you send a small number of soldiers, you won't be able to defeat the thieves and you will only demoralize your own troops. If you send a lot of soldiers, if you fail to defeat them, the city gate is narrow and the pontoon bridge is small, which will definitely lead to huge casualties!
