Cut off all retreat

Xiang Yu's vanguard troops saved the giant deer, and the first battle was less profitable. Xiang Yu led the army to cross the Zhanghe River, burning the bridge and boosting morale. Finally, Su Jiao was killed, Wang Li was betrayed, and Qin Jun was defeated in Juluchang.

Agree on the three-point rule-formulate rules that all parties concerned should abide by.

In 206 BC, Liu Bang led an army into Guanzhong. In order to win the hearts of the people, Liu Bang announced: "Abolish all the harsh laws of the Qin Dynasty. Make three laws: the murderer should be put to death, the wounded should make amends, and the thief should be convicted! " Both elders and heroes expressed their support for the three chapters of the contract. Hearing this, the people enthusiastically took cattle, sheep, wine and grain to support Liu Bang's army.

At the end of Qin Dynasty, Xiang Yu claimed to be the overlord of Chu, which violated the agreement that Xianyang was the king first. Liu Bang was extremely dissatisfied. He led his troops into Sichuan and burned the Bashu plank road along the way, making it Hanwang. With the help of Han Xin, Liu Bang built a plank road in the open, then made a detour to win Zhang Han, the general of Xiang Yu, and finally won the title of king of the Central Plains.

Liu Bang, besieged on all sides, tightly surrounded Xiang Yu. In the evening, Xiang Yu heard that all the troops around him were singing Chu folk songs, and he lost his fighting spirit. His beloved concubine committed suicide in front of Xiang Yu's horse, and Xiang Yu's hero finally became a river.
