The Chu-Han Contention recounts the historical events from 209 BC to 201 BC. After the death of Qin Shi Huang, the second emperor, Hu Hai, ruled incompetently and cruelly. The people could no longer bear their oppression and rose up in rebellion. Following Chen Sheng and Wu Guang, Xiang Yu raised an army in Jiangdong, while Liu Bang rebelled after slaying a serpent in the Mang and Dang Mountains. Acting under the orders of King Huai of Chu, they split their forces and attacked Qin along two routes. Liu Bang’s army was the first to enter Guanzhong, and Qin King Ziying surrendered, bringing the Qin dynasty to an end. Afterward, Liu Bang and Xiang Yu fought for power, plunging the land into the Chu-Han Contention. After five years of struggle, the two sides fought their decisive battle at Gaixia. Xiang Yu was defeated and killed himself by the Wu River, while Liu Bang unified China and founded the Western Han dynasty.
