What's the name of losing ten thousand enemy troops and three thousand enemy troops?

In fact, it is a practice that harms others and does not benefit others. On the surface, it seems that seven wins and three losses are actually losses.

If you kill ten thousand, you will lose three thousand. If you win without fighting, you will win. )

Sun Tzu said:

The art of war is the best in the country, followed by breaking the country; The whole army is the best, followed by Pojun; The whole brigade is the best, followed by the broken brigade; The whole army is the best, followed by broken soldiers; All Wu is the best, followed by breaking Wu.

Therefore, it is invincible, neither good nor good; Defeat the enemy's soldiers without fighting, and the good ones are also good. (If you kill 10,000 enemies, you will lose 3,000. If you win without fighting, you will win a total victory. Therefore, you will attack the army first, then cut the enemy, then cut the soldiers, and then attack the city. The method of siege is the last resort.
