The winner is the king and the loser is the bandit. This is a common thing for military strategists. Liu Bang and Xiang Yu were originally allies who shared the same enemy. They defeated Qin together and agreed that whoever attacked Xianyang City first would be the king. At that time, Xiang Yu's troops were stronger than Liu Bang's, but because the main Qin army was on Xiang Yu's attack route, Liu Bang invaded Xianyang first. Liu Bang, who entered Xianyang first, should have been the king, but Xiang Yu had 400,000 troops at that time, while Liu Bang only had 100,000 troops. Liu Bang did not dare to compete with Xiang Yu, the overlord of Chu, so he gave up his position as king.
But Liu Bang had great ambitions, and his desire to become king was definitely not a fantasy. Before Xiang Yu arrived in Xianyang, he bought people's hearts in Xianyang City, and many Qin people loved him very much. Facing Xiang Yu, the overlord of Western Chu, he was also able to bend and stretch. He first tried to please Xiang Yu and made him put down his guard against him. The Hongmen Banquet was a life and death situation for Liu Bang. If he was not careful, he might be killed, but he did not back down and faced Xiang Yu head-on. In this psychological war, Liu Bang was the final winner. Liu Bang relied on his extraordinary magnanimity, knowing people well, and being able to take advantage of talents, and he became the winner of the Chu-Han War as he wished.
On the other hand, Xiang Yu's military strength was almost three or four times that of Liu Bang, but he ended up committing suicide. In fact, it is not surprising that Xiang Yu failed. Just looking at Xiang Yu's character, he is not suitable for big things. He is brave, indecisive, womanly, suspicious by nature, unable to listen to other people's opinions, very irritable, and vain... ...In short, Xiang Yu's lack of victory has absolutely to do with his character.
Looking at the Chu-Han War, Liu Bang won against Xiang Yu not by luck, but by courage, resourcefulness and character.
