The last key point of Xiang Yu is his love of vanity.

First of all, Xiang Yu fully demonstrated his greed and vanity in "Hongmen Banquet". The Hongmen Banquet was a turning point for Xiang Yu, but he did not seize the opportunity. Before the Hongmen Banquet, Liu Bang asked Xiang Bo to say some flattering words to Xiang Yu. In addition, he was Xiang Yu's uncle, so it was easy to paralyze Xiang Yu. During the Hongmen Banquet, Liu Bang treated Xiang Yu like a general; he treated himself like a general. As a minister, Xiang Yu quickly and completely disarmed his thoughts in front of Liu Bang's sweet words. Finally, Liu Bang asked Zhang Liang to send the white jade, and King Xiang accepted the jade and sat on it.

After that, Liu Bang angered Xiang Yu and he apologized with gifts. When Xiang Yu heard Liu Bang's humble tone and felt that Liu Bang respected him very much and had no intention of competing with him, his arrogance and vanity became clear. Satisfied, his anger disappeared. Not only did he tell the truth about the informant, but he also hosted a banquet for Liu Bang to show his reconciliation and friendship. Liu Bang's leaving without saying goodbye at the banquet was originally a lack of etiquette, but because Zhang Liang presented a pair of white jade to Liu Bang on behalf of Liu Bang, Liu Bang satisfied his pride and vanity, so he no longer pursued it.

Secondly, Xiang Yu committed suicide in Jiangdong. "Guanzhong is blocked by mountains and rivers, and the land is fertile, and everyone can dominate it." It is enough to prove the importance of Guanzhong. However, Xiang Yu did not consider the overall situation to capitalize on Guanzhong, but gave up the rich and strategically important location for the so-called vanity capital Pengcheng. Guanzhong. Although it is said that Xiang Yu sealed the three kings of Guanzhong to prevent Liu Bang, it actually did not have much effect. Later, they were defeated by Liu Bang in turn. Liu Bang used Guanzhong as his base and finally defeated Xiang Yu. When Xiang Yu was defeated in Gaixia and broke through to Wujiang River, history gave him another chance to make a comeback. "There are so many talented people in the east of the Yangtze River, and there is no telling how they will come back." If Xiang Yu had crossed the Wu River and started all over again, maybe he would have had a chance. But Xiang Yu did not choose this opportunity. Thinking that he came out with eight thousand soldiers and now went back alone, Xiang Yu felt shameless to face Jiangdong's elders, so he chose to commit suicide. Xiang Yu is a hero, a tragic hero. He gave up the chance to make a comeback and gave up his life for the sake of so-called face.

Finally, Xiang Yu is very face-saving. In the Battle of Gaixia, Xiang Yu failed in the end. He could have tried again, but because of his face, he said: "If heaven wants to destroy me, how can I survive?" and gave up.

Xiang Yu's psychology is very fragile and cannot withstand the test of major pressure, which is also a manifestation of his lack of leadership qualities. Xiang Yu has a famous saying: "If you don't return to your hometown if you are rich and noble, you will be walking at night in brocade clothes. Who knows?" This fully exposes this guy's vanity and shallowness. Why go back to your hometown? It's just to show off to the elders in his hometown that Xiang Yu has made a difference and lives a bit like a dog! It was precisely because of this psychological mischief that he was unable to see Jiangdong's elders when he failed. He could not withstand the blows of failure and setbacks, and was on the verge of psychological collapse. The growth and birth of a great man is almost impossible without countless failures and setbacks.
