In the first year of Qin Ershi (209 years ago), his uncle Xiang Liang revolted in Wuzhong (now Suzhou, Jiangsu). After Xiang Liang was killed, he led an army to cross the river to save Zhao Wangxie, and the Battle of Julu wiped out Qin Jun's main force in Zhang Han. After Qin's death, he was called the overlord of the West Chu, and the system of enfeoffment was implemented, making Qin heroes and nobles of the six countries kings. After fighting for the world with Liu Bang, the Chu-Han War lasted for four years. In 202 BC, he was defeated and committed suicide by the Wujiang River in Gaixia (now Lingbi South, Anhui). The ancients commented on it as "brave feather, unparalleled throughout the ages", and the word "overlord" originated from Xiang Yu.
Xiang Yu's invulnerability on the battlefield is contrary to his political naivety. He killed prisoners of war, abandoned Guanzhong, missed Chu, exiled Yidi, became king on his own, but lost all hearts. The outstanding performance is in employing people. Liu Bang's Xiao He, Han Xin, Ying Bu came from different backgrounds, but they were able to give full play to their strengths, and they didn't even need a Fan Zeng. Xiang Yu 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. Military genius, political fool. But political failure can't hide Xiang Yu's military talent. At the age of 22, he fought against Qin. At the age of 27, he became a tyrant of Chu and a vassal of the 18th Route. At the age of 30, he committed suicide in Wujiang.
