《三国志·魏书·钟繇华歆王朗传》
如果孙权亲自和蜀军对峙交战，经过长久的交战，智谋相等实力均衡，战事不能迅速结束，就应该发兵以助长孙权的气势，然后应该选取谨慎稳重的将领，在敌人的要害处，等待时机然后行动，选择地点然后出兵，一举行动，就没有剩余的事了。
假使权亲与蜀贼相持，搏战旷日，智均力敌，兵不速决，当须军兴以成其势者，然后宜选持重之将，承寇贼之要，相时而后动，择地而后行，一举更无馀事。
If Sun Quan personally confronts the Shu troops in a battle that lasts for a long time, their intellect and strength are on par, the battle cannot end quickly, then we should deploy troops to boost Sun Quan's momentum, then we should select a cautious and prudent general, wait for the right moment at the enemy's most vulnerable point, choose the right location before deploying troops, once we make a move, there will be nothing left.
