兵者，詭道也。故能而示之不能，用而示之不用，近而示之遠，遠而示之近.

All warfare is based on deception. Hence, when we are able to attack, we
must seem unable; when using our forces, we must appear inactive; when
we are near, we must make the enemy believe we are far away; when far
away, we must make him believe we are near.

小失誤就麻痹一片敵人。依仗隊是驕兵。
