Xu Chu (chǔ, see Ci Hai) was named Zhongkang, and he was from Bozhou (now Bozhou, Anhui). He is more than eight feet long, with a thick waist and ten waists. He looks very brave and has great courage. When I was young, thousands of families gathered in my hometown to fight against thieves. Once, due to lack of food, I exchanged food with a thief. When the cow reached the other side, it ran back. As a result, Chu Xu dragged the oxtail with one hand and walked a hundred steps. The thief was too scared to take the cow away. From then on, I was afraid to hear Chu Xu's name in Huai, Ru, Chen and Liang. After following Cao Cao, he was mainly responsible for Cao Cao's escort work after Dian Wei's death. During the battle of Guandu, people who wanted to kill Cao Cao were found, and all the assassins were killed. In the battle of Weinan, when he was wearing heavy armor, his left hand covered his face and his right hand controlled the oars, so that Cao Cao successfully crossed the river safely. When he landed, he found that he had been hit by several arrows. When he met Ma Chao and Han Sui, only Chu Xu was allowed to accompany him. During this period, Ma Chao wanted to attack Cao Cao, but when he heard about it, he suspected that he was riding a horse, so he asked Cao Cao Hu Houan, and Cao pointed at it. The latter glared at Ma Chao and asked him to give up. When Cao Cao died, Chu Xu cried and vomited blood, and Cao Pi became the general of Wuwei, responsible for the safety of the palace. When Cao Cao succeeded to the throne, he was named as a good friend, and soon died, saying that he was strong.
