What four words did Sean say about Han Xin, telling the story of Han Xin's life?

Zhang Liang used "sharp edge" to evaluate Han Xin and tell his life. Han Xin's "edge" is obvious, which stems from his military talent. At first, he accomplished nothing and lived on the support of others. After he defected to Liu Bang, he was finally reused. He was very grateful to Liu Bang for his appreciation, so no matter what he did, he didn't choose to betray him. But in the process, he hesitated.

On the recommendation of Xiao He, Han Xin became a general under Liu Bang. Liu Bang is always disrespectful to others, but he is extremely polite to Han Xin. This is all about wooing Han Xin and making him fight for himself. To Liu Bang's surprise, Han Xin won the first battle, and then he was on a roll, successfully laying a solid foundation in many aspects.

As soon as he attacked Wei, he pretended to fight with the other side, but in fact he sent someone to sneak attack. He easily defeated Wei. Then Liu Bang sent him to attack Zhao and Daiguo. The latter is relatively small, and Han Xin soon ended the fighting. It took a little more time to attack Zhao, but the result was victory. Finally, he went to attack the most powerful State of Qi, and he finally won.

As early as when Han Xin attacked Qi, he was advised to stand on his own feet as king. After some hesitation, he still didn't betray Liu Bang. Han Xin's own military talent is too strong, but in character, he lacks the decisiveness of the king. After the establishment of the Han Dynasty, he should have kept a low profile, but he was still a little supercilious, so that he didn't even know that he had offended Liu Bang. His personality is too strong to carry his military talents, and it is more appropriate to describe him as too sharp.
