Whoever wants to arouse the masses and punish the people will do whatever it takes.

Whoever wants to stir up the masses and condemn the people must do so at the right time.

Judging from the translation of "Days of Hundred Battles", anyone who wants to mobilize the masses and conquer for the people must be based on the right time and place.

A train of thought of military strategic confrontation refers to adapting to the weather to crusade against the enemy. Liu Ji pointed out in Hundred Wars: "Anyone who wants to arouse the masses and condemn them must be at the right time. The monarch was in political chaos, the soldiers were arrogant and the people were trapped, the sages were exiled and the innocent were killed. The enemy has this trick, and the soldiers attack it and are invincible. The law says, "conquer in time. "That is to say, anyone who sends troops to attack the guilty rulers and comfort the suffering people must conform to the weather. If the monarch is fatuous, the politics is chaotic, the army is arrogant, the people are poor, talented ministers are exiled, innocent people are killed at will, and droughts, insect pests, floods and hailstorms occur, the enemy can send troops to attack them, and there is no one who fails to win. "The Art of War" says: Only by opposing the enemy according to the time can we win. This is a fact. This method of warfare is called celestial warfare.
