Of the three kingdoms, why didn't Guan Yu listen to Zhuge Liang's words, "resisting Cao Wei in the north and Wu Dong in the east"?

We all know Guan Yu. He is honest, loyal to the liver and courageous, and bent on restoring the Han Dynasty. Together with Liu Bei and Zhang Fei, they became the famous iron triangle in Taoyuan. I eat at the same table as my eldest brother Liu Bei and sleep together, which is closer than my own brother.

But since the eldest brother invited Zhuge Liang, the relationship between eldest brother Liu Bei and Guan and Zhang is not as close as before. Eldest brother accompanied Zhuge Liang every day, keeping watch and hanging aside. Guan Yu, a village man invited by his eldest brother, is full of anger. Now that he is in this field, he is even more angry.

Guan Yu prides himself on his ability to kill Hua Xiong with warm wine and Yan Liang and Wen Chou. Few people can get Guan Yu's attention, especially the scholar-bureaucrat class, let alone a village man and scholar-bureaucrat. By this time, Guan Yu and Zhuge Liang had made an issue.

Of course, I won't listen to Zhuge Liang's strategy of resisting Cao Wei in the north and Wu Dong in the east. Guan Yu is a military commander, thinking everything on his face, while Zhuge Liang is a civilian, and no one knows what he thinks.

Let's see how Zhuge Liang gave Guan Yu a difficult problem:

First, Battle of Red Cliffs, Sun and Liu defeated Cao Cao, Cao Cao defeated Huarong Road, and Zhuge Liang sent Guan Yu to guard Huarong Road. Guan Yu always thought that Cao Cao was good to him. We often say that he is Guan Yunchang, who once lived in America, and Guan Yu is the most loyal. In his style, he can't kill Cao Cao, but what would Guan Yu think if he let Cao Cao go? Liu Bei must beware of Guan Yu. Kong Ming's move can be described as killing two birds with one stone, alienating the relationship between Liu Bei and Guan Yu, and at the same time cleaning up Guan Yu a little.

Second, Soochow sent Zhu Gejin to propose marriage. Zhu Gejin is Zhuge Liang's younger brother. Zhu Gejin said that Guan Yu had a daughter, and Sun Quan wanted to be Guan Yu's in-laws. This was flatly rejected by Guan Yu, who also said that a tiger girl could marry a son, so that Guan Yu offended Sun Quan. To say the least, if Guan Yu agrees to this marriage, what will Liu Bei think? Will Liu Bei think that Guan Yu has ulterior motives? Will Soochow take Guan Yu's daughter hostage?

Third, the battle of Xiangfan, Zhuge Liang knew that the conditions for the battle of Xiangfan were not mature and wanted Guan Yu to fight Xiangfan. At the same time, it also violates Longzhong's strategic thinking. Moreover, when Guan Yu was caught between Scylla and Charybdis in the battle of Xiangfan, Liu Bei and Zhuge Liang did not send a single soldier to support Guan Yu, which led to Guan Yu's defeat and beheading in Maicheng. Zhuge Liang cornered Guan Yu step by step and killed him with the help of Soochow. With a wave of his sleeve, Kong Ming didn't take away a cloud, which made him sit in the second place in the Shu-Han regime, becoming the closest and most influential person to Liu Bei.
