1, Xiang Yu is a proud man at heart. He thought he could lift the tripod from beginning to end, and he thought he was an unparalleled hero, but he was finally defeated by Liu Bang, who he considered a "sinister villain". He was unwilling and depressed. I think he is such a proud man. Strong frustration should be one of the main reasons for his suicide.
He always believed that he could "make a hero with the times", but in the end he had to admit that "the times make a hero". He gave up, felt that there was no point in living any longer, and committed suicide.
After the failure, he realized that the result was all caused by his own stubbornness. He was speechless for the elders in Jiangdong and committed suicide.
4. The death of concubine Hong Yan hit him hard. He feels that he can't even protect the woman he loves, how to be a great hero and how to become the king of a country. So he finally committed suicide with Ji's heavenly sword and died with her.
Fan Yafu always said that Tianzijian was an ominous thing. Many emperors in the previous dynasties used it to commit suicide. Xiang Yu never believed it. He tried to change his fate and defeat Liu Bang, who was destined to be, but ended in failure. At the last moment, he had to believe in fate and that he could not resist fate and Liu Bang, so he committed suicide.
6. From another perspective, Xiang Yu thinks his failure is obvious. If he comes back, it will only increase the killing and make the whole world miserable. If he doesn't want to kill more people, he will kill himself.
7. Xiang Yu has a lot of backbone. He knew that if Liu Bang didn't commit suicide, he would try his best to kill him. He felt that instead of worrying about others killing himself all day, he might as well die with more backbone and commit suicide.
8. Apart from being attracted by power, he should also sincerely want to make the people at dawn live a better life. He lost, but he believed that Liu Bang would take care of the world. He felt tired and didn't want to kill again, so he committed suicide and went to accompany his concubine.
9. He always regarded Liu Bang as his good brother, but after the negotiation, the good brother betrayed himself. He was very sad and committed suicide.
