Xiang Yu saw that he was defeated by Liu Bang on the battlefield, so he told Liu Bang in a rage that he would fight alone and whoever won the land would belong to him. Liu Bangcai didn't fall for it. He would rather be a coward and be scolded than fight with Xiang Yu. In terms of brains, Xiang Yu really lost to Liu Bang. In the end, Liu Bang also defeated Xiang Yu with tricks.
Xiang Yu heard that Liu Bang had pacified the Guanzhong area on his way to the State of Qi, and immediately sent his subordinate Zheng Chang as the king of Korea to attack Liu Bang. At this time, Sean, Liu Bang's counselor, forged a spy letter from Zheng Chang to Xiang Yu, saying that Liu Bang only wanted to gain a foothold in Guanzhong, and did not covet the mind of Xi Chu. So Xiang Yu believed it, which has to be said that Zhang Liang is too awesome. He only used a pen and a piece of paper and didn't move a single soldier, thus avoiding the battle. It can be said that it is strategizing and winning thousands of miles.
Xiang Yu concentrated on attacking Qi, and it was not easy to fight, because Xiang Yu had offended the people of Qi before, so in the face of Xiang Yu's attack, Qi Xin, the people of Qi, joined forces to resist Xiang Yu. After the battle, it was found that Liu Bang had occupied Cheng Peng, Xiang Yu's lair. Xiang Yu immediately led his troops to fight back and caught Liu Bang off guard. Although Liu Bang lost, during this period, Liu Bang killed many soldiers of Xiang Yu, including glad that you came. Just after playing Pengcheng, Liu Bang occupied the elevation again. Xiang Yu had no energy to fight any more, so he asked Liu Bang to fight one-on-one, but Liu Bang was too stupid and naive to refuse Xiang Yu.
