Cao Cao was the most powerful tyrant of the Three Kingdoms period, occupying most of the Central Plains and the north, and his men were full of talents. Cao Cao did everything in order to get talent, when Xu Shu defected to Liu Bei, cao Cao used Xu Shu's mother to threaten xu shu in order to get Xu Shu, forcing Xu Shu to come to Cao Camp. However, there is one person Cao Cao has always wanted to get, but in the end he has not been able to get it, he is Guan Yu. Cao Cao admired Guan Yu very much from the beginning of Guan Yu's warm wine and HuaXiong, and always wanted to get it. How fierce was Guan Yu in Cao Cao's heart? Only four people could resist him, and Cao Ying had only one.
The first is Lü Bu, the first fierce general of the Three Kingdoms, Cao Cao personally witnessed Lü Bu's strength, and Lü Bu failed to kill Lü Bu before the Tiger Prison Pass, which shows Lü Bu's bravery. Later, Lü Bu fought with Cao Cao and put Cao Cao in danger several times, and later Cao Cao captured Lü Bu, although he knew that Lü Bu was a man who had betrayed his faith many times, but he was still a little hesitant to kill him, and in Cao Cao's heart Lü Bu was able to compete with Guan Yu. The second is Zhang Fei. When Zhang Fei shouted loudly and frightened Cao Cao's army to retreat at the speed of light, it could be seen that all the generals under Cao Cao were very jealous of Zhang Fei's bravery. After all, it was someone who had once fought with Lü Bu, and no one dared to underestimate it. Cao Cao was also more afraid of Zhang Fei and did not dare to fight with him.
The third place is Xi Liang Ma Chao. In order to avenge his father's revenge, Ma Chao led a large army to fight against Cao Cao, and once killed Cao Cao to cut off his robe, if it were not for someone to risk death to save him, Cao Cao would have been killed by Ma Chao long ago. Cao Cao once lamented that Ma Chao did not reduce the courage of Lü Bu that year, and several generals were defeated by Ma Chao in turn, and Ma Chao was also able to compete with Guan Yu.
The last was Cao Cao's general Cao Ren, a brilliant military figure who was not only strong in force, but also good at commanding large armies, and Cao Ren repeatedly served as a defensive task in important areas. At that time, Guan Yu attacked Fancheng, and the general who guarded the town was Cao Ren, who was sent by Cao Cao to defend Against Guan Yu in Jingzhou, so in Cao Cao's view, Cao Ren's ability was not inferior to Guan Yu.
