Wait for that moment
when the enemy weakens.
Use the other side
Luring him into a trap.

“Attacking the most impregnable fortresses is a bad strategy.”
(Sun Tzu)

To attack a strongly defended position is to doom yourself to defeat. The temptation to instantly get more can turn against you. It is better to wait until the enemy exhausts his strength. Then you need to use all available resources to conquer it. Such a victory will take more time, but will strengthen positions and reduce losses.

Han Xin had previously been a supporter of Xiang Yu, Liu Bang's main rival for the imperial throne. Subsequently, he went over to Liu Bang's side and became his military leader. As a token of gratitude, Liu Bang appointed him head of the kingdom of Chu.

However, after some time, Han Xin refused to carry out Liu Bang's direct order. He sheltered a major enemy commander and began plotting a rebellion. By that time, Liu Bang had become the Emperor of China and he needed to neutralize the traitor to prevent an uprising. To do this, he decided to use a strategy.

Liu Bang arranged an inspection trip to Yunmeng and convened all his appanage princes for a council. When Han Xin received this invitation, he had no choice but to comply. He was afraid of being accused of rioting. To avoid this, he came to the council with the head of the military leader, thereby trying to prove his loyalty to the emperor. But this had no effect and Han Xin was arrested.

In this example, the council of princes served to remove Han Xin - the “tiger” from his inheritance of Chu - the “mountain” and easily neutralize him. Liu Bang used a strategy to act effectively in a difficult situation and not lead to an armed uprising.
