At the beginning of the Han Dynasty, Liu Bang, who was named Hanwang, used the strategy of general Han Xin to sneak into Chencang and captured the Guanzhong area (now Shaanxi area), the hometown of Qin State, which laid the foundation for the eastward expedition of Xiang Yu, the overlord of the western Chu State. Subsequently, Liu Bang gradually moved eastward from Guanzhong and launched a long-term stalemate with Xiang Yu in today's Henan, Anhui and other places. At the same time, Liu Bangpa Han Xin led some troops to cross the Yellow River and make war with Wei, who was pro-Chu. Wei was captured by Han Xin and Wei Bao in the southwest of Shanxi. Then, Han Xin continued to attack Zhao Wangxie eastward, because his general Chen Yu did not listen to Li Zuoche, the general of Guangwu Emperor, and captured Zhao Wangxie in Jingxing (now Jingxing County, Hebei Province, at the junction with Shanxi Province), Chen Yu was killed and Li Zuoche was captured alive. Han Xin appreciated Li Zuoche's talent very much, treated him well and asked him for advice, but Li Zuoche said, "A failed general should not be brave." It means loser or hero! Han Xin smiled and said, "You're welcome, sir. If Chen Yu listens to you, then I will be a failed general. " This is the origin of the idiom "loser".
