Summary of historical evaluation: Xiang Yu was invincible on the battlefield, politically naive and even stupid. Pit and kill prisoners of war, give up Guanzhong, miss Chu, exile Yidi, stand on one's own feet, and lose people's hearts. The more outstanding performance is that Liu Bang's men, Xiao He, Han Xin, Ying Bu, come from different backgrounds but can give full play to their strengths, and Xiang doesn't even need a Fan Zeng, which is in sharp contrast with Liu Bang. Later, the demise of Soochow in the Three Kingdoms period also showed that Jiangdong was unstoppable when there was only Jiangdong left in the world. According to Mr. Wang Liqun of Henan University, "Xiang Yu is a very useful person, but he sits in the position of employing people". This is Xiang Yu's sorrow. But political failure can't hide Xiang Yu's military talent. At the age of 24, he fought against Qin. At the age of 27, he became the overlord of Chu, a vassal of the 18th Route Army. At the age of 30, he committed suicide in Wujiang. He is a worthy hero. He is different from the emperors and princes in the history of China. He is just a tyrant of Chu.
