In 207 BC, Xiang Yu, the overlord of Western Chu, defeated the Qin army, revived the state of Chu, and became the strongest prince. It stands to reason that Xiang Yu has the strength to defeat Liu Bang, and then submit the princes to unify the world; But Xiang Yu didn't do that. Since Xiang Yu is so powerful, why can't he still dominate the world?
Xiang Yu's ambition is to "destroy Qin and restore Chu", not to dominate the world; If Xiang Yu really wanted to dominate the world, he would not have killed 200,000 Qin soldiers, and he didn't care about the people's wishes at all. Moreover, Xiang Yu also abandoned the county system of the Qin Dynasty, and then restored the sub-feudal system of the Zhou Dynasty.
Fan Zeng is the most important advisor under Xiang Yu's account, but Xiang Yu is too rigid and self-serving, and he repeatedly refuses to listen to him; For example, Fan Zeng once suggested that Xiang Yu kill Liu Bang, but Xiang Yu was soft-hearted and did not do so, and finally let the tiger return to the mountain and let Liu Bang become bigger and stronger, these are all Xiang Yu's character flaws.
In addition, when Xiang Yu's army defeated Wujiang, he did not choose to flee to Jiangdong, but drew his sword and killed himself; How can a person who cannot endure a momentary humiliation rule the world?
In fact, Xiang Yu has the strength to dominate the world, but many opportunities were missed by him in vain, and he gave Liu Bang, the king of Han, a chance to take advantage of; was finally defeated by a person who was most despised, and Xiang Yu, who didn't know what Wujiang was killing himself, how should he feel?
