Guan Yu was a famous general of Shu Han during the Three Kingdoms period. It was said that his real name was Guan Ping, and he was one of the important advisors of Liu Bei, the last emperor of Shu Han during the Three Kingdoms period. Guan Yu was born into a military family and had been trained strictly since he was young. He was good at horse fighting. According to the Romance of the Three Kingdoms, before Liu Bei recruited Guan Yu, he had been a general guarding his hometown for a period of time. Later, Liu Bei recruited him and let him join his army. Guan Yu had performed well in Liu Bei's army and was known as the "Tiger General" because of his bravery and fighting skills. After Liu Bei captured Yizhou and Jingzhou, Guan Yu was promoted to General Zhendong and served as the herdsman of Jingzhou. During his time in Jingzhou, he had helped Liu Bei defeat the enemy many times, including the generals of Cao Wei, Zhang He and Ma Teng. In the end, Guan Yu was surrounded by Cao Ren, a general sent by Cao Cao, but he successfully broke through and surrendered to Liu Bei. Liu Bei was grateful for Guan Yu's help and gave him the title of "General Yi De" and appointed him to defend the northern border of Shu Han. Because of this, Guan Yu became one of the most famous generals in the history of Shu Han. However, there were also some literary works and film and television works that exaggerated and beautified Guan Yu's image to make him look even more brave. However, Guan Yu was indeed an outstanding general in history, and his brave image was also reflected in historical records to a certain extent.
