《梁书·列传·卷十》
如果受到仁德的感召。就能万里归心远迩归义，加上平时多加蓄积财物，粮食的运送又很充足，那么就可以列围宽守，延长时间，造就是王翦之所以战胜楚国的办法如果围困而不能使敌人马上投降，进取不能取胜，反问之计行不通，平时没有积蓄财物粮食，天下列强争雄，人心难以预料，那么就应该再想想其他的变通办法了。
若德之所感，万里同符，仁之所怀，远迩归义，金帛素积，粮运又充，乃可以列围宽守，引以岁月，此王剪之所以克楚也。若围之不卒降，攻之未可下，间道不能行，金粟无人积，天下非一家，人情难可豫，此则宜更思变计矣。
If you are influenced by kindness, you can make people from far and wide loyal to you and go along with what you demand, and if you also save up money and provisions, and if the supply of food is sufficient, then you can set up wide sieges, extend the time, and create the way that Wang Jian defeated the state of Chu. But if the siege can't make the enemy surrender right away, if you can't win a decisive victory if you attack, if you can't apply the strategy of counterattack, and if you didn't save up money and provisions, and if the major powers are competing and people's hearts are hard to predict, then you should think again about other ways to outsmart the opponent.
