After Battle of Red Cliffs, Cao Cao was burned back to his hometown by Zhou Yu, and the Sun-Liu alliance collapsed and began to compete for Jingzhou. Cao, the boss who washed black ashes in Chibi, heard about it and couldn't sit still again. He immediately called a meeting of ministers, hoping to participate.
Yu Xun plausibly said to Cao Cao, "Sun Liu's fight for Jingzhou is like two dogs fighting for bones. Not only do not interfere, but also give the bones to the weak dog. The strong dog will definitely get angry, and will continue to chase and bite, and the snipe and clam will compete and not give way to each other. Wouldn't it be better for us to be a cheap melon eater? " Hearing Yu Xun's remarks, Cao Cao was hit hard, beaming instantly, laughing, and before he could express his joy, he sat in the temple and called three times like a dog. Your Highness, only Chu Xu laughed and everyone else was silent. So why is Cao Cao so partial to Chu Xu, while Chu Xu dares to behave in front of Cao Cao? This must start with Chu Xu's nickname "Tiger Idiot".
The word "tiger" in Chu Xu's nickname naturally praises his amazing fighting capacity. Chu Xu has the ability to drag the oxtail back, but he is not brave enough. When I first met Cao Cao, as a mixed weapon, he was able to fight Dian Wei, Cao Cao's most proud general, for hundreds of rounds, which surprised Cao Cao!
After surrendering to Cao Cao, Chu Xu fought side by side with four generals of the Five Tigers in West Shu. Because drinking and fighting with Zhang Fei is not a mistake. Except for losing to Guan Yu, Zhao Yun and Ma Chao were tied. Ma Chao was even defeated by Chu Xu. Once he tried to assassinate Cao, but when he saw him around, he thought for a long time and dared not do it. Luo Guanzhong praised Chu Xu in the Romance of the Three Kingdoms: "After Ge Bei and Chu Xu surrendered, why worry about Lu Buqiang!" How could Cao not love such a valiant soldier?
Chu Xu's IQ is not high and his mind is simple. After he surrendered to Cao Cao, only Cao Cao was in his heart. He took Dian Wei's class and served as Cao Cao's escort, but also cared about Cao Cao's safety to the point where he was almost connected with Cao Cao. In the battle of Guandu, an assassin assassinated Cao. When Chu Xu returned to his tent, he suddenly became flustered. When he returned to Cao Cao's tent, he found an assassin. In the battle of Weinan, he paddled with one hand and protected his head with the other. There are many experiences in protecting Cao Cao like this. It can be said that without Chu Xu, Cao Cao's life would not have been lost. When Cao Cao died, Chu Xu cried until he vomited blood, which shows that he really loved Boss Cao!
