Soldiers have no constant potential and water is impermanent, which is an ancient thought of using troops. It means that in leading troops, we should adopt flexible strategies and tactics according to the changes of the enemy's situation, and we should not stick to a certain combat method. From "Sun Tzu's Virtual and Real Articles".

brief introduction

"Sun Tzu's Virtual and Real Articles": "The image of husband and soldier is water, in the shape of water, avoiding heights and descending; The shape of a soldier, avoiding reality is empty. Water flows because of the ground, and soldiers win because of the enemy. Therefore, the soldiers have no constant potential and the water is impermanent; Being able to win because of the change of the enemy is also called God. " This sentence has always been called the famous saying of flexible command of war.

There is no fixed way to lead troops to fight, just as the current has no fixed shape, it can win according to the changes of the enemy's situation, which is called leading troops like a god.
