Before meeting Xiang Yu, Yu Zi lived mainly by selling weapons. At that time, he constantly revolted to overthrow the tyranny of Qin Ershi, so there was a general shortage of weapons. Many insurgents hoped to have someone especially trustworthy to provide them with weapons, so at that time, life in Yu Zi was still very good. After meeting Xiang Yu, his life changed completely, from business at the beginning to martial arts. Fortunately, Yu Zi's martial arts were still very good. Yu Ziqi and Xiang Yu are strangers. Yu Ziqi lost, but she lost happily. He took Xiang Yu home, introduced his sister to him, and promised him that he could provide weapons to Xiang Yu continuously. On another level, Yu Ziqi's behavior can be said to show his attitude and choose his own political position. Since then, Yu Zi began to fight with Xiang Yu in the south and north. They spent many difficult times together, and during the Yu Zi period, they fought for Xiang Yu constantly on the battlefield. Because of Liu Bang's deviance, many people around Xiang Yu were unfaithful to him, but during the Yu Zi period, he never doubted and even trusted him very much. He handed over the military power to him in the most difficult time. Finally, when Xiang Yu committed suicide in Wujiang River, Yu Ziqi was by his side, and Yu Ziqi himself died in the battle of Wujiang River.
I am a hero. He is not as famous as Xiang Yu, but he has the pride and achievements of nobody.
