《孙膑兵法·十问》
 两军对垒时，敌方很富，我方很穷，敌军兵多，我军兵少，敌强我弱，敌军用方阵向我方进攻，我军该如何抗击敌军呢？ 
交和而舍，敌富我贫，敌众我少，敌强我弱，其来有方，击之奈何？
When the two armies are fighting against each other, the enemy is rich and we are poor, the enemy has many soldiers and we have few soldiers, the enemy is strong and we are weak, and the enemy uses a square formation to attack our side, how should our army resist the enemy?
