《淮南子·兵略训》
但反过来，敌人由运动返归宁静，那么我方就非得出奇招不可了；敌方如对我方奇招不理不睬，那么我方就可独自完成自己的调整；如果敌方有了反应，那么我们也就能在这当中观察到他们的意图了；如果敌方后于我们行动，控制了我方的行动，那么我方就要想尽一切办法在与他们周旋之中摆脱困境；敌方如集聚部队追打我方，那么他的后方也必定虚空；敌方的精锐部队在左方，那么我军就可攻击他的右方。
敌若反静，为之出奇，彼不吾应，独尽其调。若动而应，有见所为，彼持后节，与之推移。彼有所积，必有所亏，精若转左，陷其右陂。
But conversely, if the enemy returns to tranquility from motion, then our side must come up with strange tactics; if the enemy ignores our strange tactics, then our side can complete its own adjustment; if the enemy reacts, then we can also observe their intentions in this time; if the enemy takes action after us, and controls our actions, then our side must think of every way to get out of trouble in the midst of dealing with them; if the enemy concentrates forces to pursue us, then his rear must be empty; if the enemy’s elite troops are on the left, then our army can attack the right.
