Xiang Yu was born in the military nobility of Chu. The original purpose of his rebellion with his uncle was to destroy Qin and avenge Chu. In fact, Xiang Yu and Sean had the same original intention. The difference is that Sean is a counselor and Xiang Yu is a leader. After Xiang Yu destroyed Daqin, he set fire to Xianyang, which was a kind of evil spirit for Chu people. So if he takes Xianyang as his capital, then his capital will become the target of Qin people's attack, which means that Xiang Yu will have no peace in Xianyang.
Before Xiang Yu entered the customs, he agreed in front of Wang Huai that Wang Guanzhong was the first to enter the customs. Since the death of Xiang Liang, Xiang Yu has been marginalized. Chu Huaiwang not only held the relieving in his own hands several times, but also got a Song Yi to control Xiang Yu. With his uncle's prestige and courage, Xiang Yu regained the military power again, which led to the battle to kill Song Yi and Julu. However, Chu Huaiwang, as a symbol of supreme power, should take his words into account even if he doesn't listen. Xiang Yu deeply knew that he was able to lead the army into Guanzhong and become commander in chief, which had a lot to do with his being a Truman, and Chu Huaiwang was the spirit of uniting the Truman, so even if Xiang Yu wanted to make Xianyang his capital, he was unable to do so.
Moreover, Pengcheng is more suitable to be the capital of Xiang Yu than Xianyang. In Pengcheng, Xiang Yu had the mass base of Chu people. He destroyed the Qin Empire and was a hero of Chu people. Moreover, Pengcheng's geographical position is more suitable for Xiang Yu to control other C.
Pengcheng is connected with Sanchuan, so it is easy to send troops to control Sanchuan, which is the lifeblood of controlling the land of Sanqin, so Xiang is well guarded against Liu Bang in Pengcheng.
Pengcheng is a fortress competing for the Central Plains and a military town connecting the north and the south. Here, the soldiers are refined and the people have their wishes. How is Xianyang compared?
The fundamental reason for Xiang Yu's failure is not the failure of employing people, nor the failure of the strategy of building the capital, but the failure of choosing opponents. When Liu Bang decided on Sanqin, if Xiang Yu's westward march directly helped Zhang Han to eliminate Liu Bang and let Long Qie and others entangle Tian Rong and Peng Yue, there would be no later Wujiang River committing suicide.
