Three plots of Guan Yu in Romance of the Three Kingdoms correspond to 2 characters.

In 215 AD, Liu Bei took Yizhou, and Sun Quan ordered Zhu Gejin to ask Liu Bei for Jingzhou. Liu Bei refused, and Sun Quan was very angry, so he sent Lu Meng to take Changsha, Lingling and Guiyang. Changsha and Guiyang Shu will surrender immediately. When Liu Bei learned of it, he personally rushed to the public security from Chengdu (now Hubei Public Security) and sent General Guan Yu to compete for the three counties. Sun Quan also immediately stationed in Lukou and sent Lu Su to station troops in Yiyang to resist Guan Yu. At this critical juncture, in order to maintain the Sun-Liu alliance and not give Cao Cao an opportunity, Lu Su decided to discuss with Guan Yu face to face. "Su invited Yu to meet each other, and each of them was stationed in a hundred paces, but all the generals were single-handedly." After talks, the two sides eased the tension. Subsequently, Sun Quan and Liu Bei agreed to divide Jingzhou equally, and "cut the Xiang River as the boundary, so the army went on strike", so the Sun-Liu alliance could continue to be maintained.

Cao Cao recruited troops and joined forces with Yuan Shao, Gongsun Zan and Sun Jian to attack Dong Zhuo. Liu Bei, Guan Yu and Zhang Fei went with Gongsun Zan. Hua Xiong, the general of Dong Zhuo, defeated Sun Jian, the pioneer of the 18th Route Army, and killed two generals before the battle. He was very proud. The 18-route warlord was in a panic and was at a loss. Yuan Shao said, "It's a pity that my generals Yan Liang and Wen Chou are not here, otherwise, I wouldn't be afraid of Hua Xiong." As soon as the voice fell, Guan Yu shouted, "Young man is willing to cut off Hua Xiong's head!" Yuan Shao thought Guan Yu was just a horse archer, so he said angrily, "We have hundreds of generals in the 18th Route, but we have to send a horse archer to battle. Wouldn't it make Hua Xiong laugh?" Guan Yu said loudly, "If I can't kill Hua Xiong, please cut off my head." Cao Cao listened to this and appreciated it very much. He poured a cup of hot wine and handed it to Guan Yu, saying, "General, drink this glass of wine before you kill the enemy." Guan Yu took the glass, put it on the table and said, "Drink it when I come back!" " Say that finish, carrying a broadsword on the horse. Guan Yu was skilled in martial arts, and soon he cut off Hua Xiong's head. When he returned to the barracks, Cao Cao picked up the glass on the table and handed it to him. The wine in the glass was not cold yet.
