Guan Yu, also known as Changsheng, was originally from Hedong. He followed his elder brother Guan Yu to join Liu Bei. Under Liu Bei's leadership, Guan Yu made great achievements on the battlefield. Among them, the legend of how Guan Yu killed Hua Xiong while drinking warm wine became an immortal tale.

According to 'Romance of the Three Kingdoms,' Hua Xiong was a general sent by the emperor to suppress the Yellow Turban Rebellion. He was very powerful and famous. One day, when Zhang Fei was fighting Hua Xiong outside Luoyang, Guan Yu suddenly appeared and the two sides fought fiercely, but neither could gain the upper hand. At this moment, Guan Yu lifted a pot of warm wine and said boldly, 'I will slay Hua Xiong and present his head to the general!' He drank the wine in one gulp and charged into the enemy's formation on horseback. Hua Xiong was not afraid and immediately went to fight him. The two sides were deadlocked. Suddenly, Guan Yu cut off Hua Xiong's head with one stroke and won the battle.

This classic battle in history not only demonstrated Guan Yu's courage and bravery, but also showed his loyalty to Liu Bei and the country. Through such struggle and sacrifice, Guan Yu became one of the greatest heroes in Chinese history.
