Immediately after Chu and Han, Xiang Yu left Xianyang. Why? Xianyang gave it to Liu Bang.

After Xiang Yu entered Xianyang, he had no intention of staying in Guanzhong. Someone advised him that Guanzhong would win and become the king of Guanzhong. As a result, he replied: a gentleman is a great man, and he doesn't go back to his hometown, just like a person walking in the night wearing gorgeous clothes. After the man came out, he secretly said that people said that the Chu people were crowned with monkeys, and it really happened. Unexpectedly, this sentence reached Xiang Yu's ears, and he cooked the man.

Before the invasion, Chu Huaiwang had made an appointment, and whoever advanced to Xianyang would enter Qin Wang. Xiang Yu named Liu Bang as Hanwang, that is, Hanzhong (also Qin), mainly in the southwest of Shaanxi today. Pass is divided into three parts, respectively, to Yong Wang Zhang Han, Sai Wang Sima Xin, Zhai Dongming, let them monitor Liu Bang.

Liu bang went to Hanzhong, turned over the Qinling Mountains, burned all the original plank roads, paralyzed the three kings, and seemed not ready to come out. A few years later, he sent someone to repair the plank road. The three kings laughed when they learned of the danger, and they didn't know how to fix it until the Year of the Monkey. . So, under the counsel of Han Xin, Liu walked out of the crossing of Chen Cang and just embarked on the famous path in history-Guanzhong. From then on, I had the capital to compete with Xiang Yu for the world. . .

There are Hangu Pass in the Middle East, Xiaoguan Pass in the north, Wuguan Pass in the south and Big Three Pass in the west. Before Liu Bang left Chencang, there were only Hanzhong and Shudi, and there was no Xianyang. Sometimes TV plays are made up. Don't take them too seriously.
