《百战奇略·第五卷·虚战》
凡是对敌作战，如果我军兵力弱，就要伪装成实力强大的样子，让敌人摸不清虚实，敌人必定不敢轻易与我交战。这样，我就可以保全实力不受损失。
凡与敌战，若我势虚，当伪示以实形，使敌莫能测其虚实所在，必不敢轻与我战，则我可以全师保军。
In any battle, if our army is weak, we should pretend to be strong, so that the enemy cannot tell the truth from the false, and the enemy will not dare to fight us easily. In this way, we can preserve our strength and not suffer losses.
