After Xiang Yu defeated Zhang Han and forced him to surrender, he also led his troops straight to Guanzhong. Fan Zeng persuaded him to take the opportunity to get rid of Liu Bang, an opponent, and Xiang Yu ordered preparations to attack the next day. At this time, Liu Bang could not compete with the powerful Xiang Yu in terms of troops, he only had 100,000 troops, and it was impossible to defeat Xiang Yu's 400,000 elite soldiers. Finally, Xiang Yu's uncle Xiang Bo; Saved Liu Bang: Xiang Bo and Liu Bang's advisor Zhang Liang were very good, and when they saw that Xiang Yu was about to attack, they sneaked into the camp overnight to find Zhang Liang and told him to leave quickly to avoid being killed. Zhang Liang said that he couldn't leave Liu Bang, so he revealed the news to Liu Bang. In a panic, Liu Bang hurriedly asked Zhang Liang for advice, and Zhang Liang asked Liu Bang to hurry up to see Xiang Bo, explaining that he had no ambition to compete with Xiang Yu for the throne.

Liu Bang made an appointment with Xiang Bo according to the plan, explaining that he had no ambition to be the king, and made an appointment with Xiang Bo to become his sons and daughters. Xiang Bo returned to the barracks that night, and he said to Xiang Yu: Because Pei Gong entered the pass first, and removed the obstacles to our entry, we can pass through the Hangu Pass smoothly, Pei Gong is a meritorious person, we should not suspect him, we should treat each other sincerely. Xiang Yu heard this, and decided not to attack Liu Bang again.

The next day, Liu Bang came to Xiang Yu's military camp, bringing only Fan Xu, Zhang Liang and a hundred elite soldiers. When he arrived at Xiang Yu's big tent, he apologized to Xiang Yu who greeted him in person. Xiang Yu invited Liu Bang to the banquet, Xiang Yu's father Fan Zeng, who had always advocated killing Liu Bang, repeatedly signaled Xiang Yu to give orders at the banquet, but Xiang Yu hesitated and silently refused. Fan Zeng summoned Xiang Zhuang to dance the sword to cheer up the banquet and took the opportunity to kill Liu Bang, and Xiang Bo also drew his sword and danced to protect Liu Bang, covering Liu Bang, but without success. This is the origin of Xiang Zhuang's sword dance, which is intended for Pei Gong. Later, Liu Bang left under the pretext of leaving and returned to the camp.

At the Hongmen banquet, Liu Bang showed a high degree of composure and calmness. To be able to retreat with his whole body, in addition to the efforts of Zhang Liang, Xiang Bo, and Fan Xu, the key is Liu Bang's calmness and composure.

After the Hongmen banquet, Xiang Yu led his troops westward, Xiang was registered in Xianyang, burned Afang Palace, and killed the prince of Qin. Liu Bang was named the king of Han, and the territory was Ba, Shu and 41 counties of the Han Dynasty, and the capital was Nanzheng. And sealed the Qin generals Zhang Han, Sima Xin, and Dong Fei as the king of Yong, the king of Sai, and the king of Zhai, and led the central land to contain Liu Bang. At the same time, Liu Bang's army was reduced to 30,000. Xiang Yu proclaimed himself the overlord of Western Chu and held the supreme command of the army. Xiong Xin, the king of Chu Huai, was revered as the righteous emperor. Later, Xiang Yu moved Emperor Yi to Chenxian and killed him.

Xiang Yu's separation, on the surface, seems to be rewarding meritorious deeds, but in fact, it is a recombination of the forces of the original princes, and the obedience is rewarded separately, and the strength and influence of the original princes in their own country are not taken into account. Therefore, the source of chaos was planted from the beginning. Moreover, he rejected the advice of the strategist Ziwang Guanzhong and resolutely returned to his hometown.

In February of the first year of the Han Dynasty, the princes boycotted the play and returned to China. Liu Bang had no choice but to swallow his anger and accept the title, and in April he led his troops into Hanzhong and burned the plank road to show that he had no intention of going east again, so as to paralyze the Xiang nationality. Tian Rong, a descendant of the nobles of the Qi State, was dissatisfied with the separation, drove away the king of Qi, killed the king of Jiaodong, and established himself as the king of Qi. Liu Bang took the opportunity to wave his army to the east, worshiped Han Xin as a general, repaired the plank road in the Ming Dynasty, secretly crossed Chencang, returned to Guanzhong, and soon defeated Zhang Han, forced to land Sima Xin and Dong Peng, and deceived Xiang with tricks, so that he believed that he was satisfied after obtaining Guanzhong, and would never go east again. Xiang Ji was relieved to attack Tian Rong, and did not strengthen his precautions against the west. In the end, they fell into the quagmire of Qidi and could not get out. This gave Liu Bang a great opportunity.
