Why was Guan Yu able to intimidate China and frighten Cao Cao into moving the capital?

The Battle of Xiangfan is Guan Yunchang's most wonderful solo exhibition and his last solo exhibition. The historical background at that time was like this. After Liu Bei borrowed Jingzhou, Jingzhou was left to Guan Yu, who began to resist Cao Cao's March in Jingzhou and his basic diplomacy with Soochow.

Later, Cao Cao sent troops to attack Guan Yu, Guan Yu's soldiers surrounded Xiangfan, and the battle of Xiangfan began. It was impossible to attack for a long time. As a result, the weather was beautiful, and it rained for ten days, which caused the Hanshui River to skyrocket. Guan Yu dug up the levee and led the Hanshui River to fill the city. This is the famous flooded seventh army. Later, he escaped from the pound ban and Cao Cao's southern portal was opened.

The victory of this battle was actually very unexpected, because at that time, neither Cao Cao nor Liu Bei, nor even Guan Yu himself, thought that he could win this war so cleanly. But Cao Cao didn't expect it, so he didn't have an army to defend the south at the moment, and Guan Yu was particularly keen on fighters. When he discovered that Monroe was ill in Wu Dong, he directly launched an army attack on Xudu.

And perhaps it is the emperor's driver's seat. As long as Guan Yu broke Xu and took the son of the Han family, Cao Wei's plan of praising the son of heaven was basically ruined. Although Cao Cao was already in Wang Wei at that time, he still needed to rely on the son of the Han family to have an orthodox name, so when the army could not stop him, he planned to move the capital and take the son of the Han family away, so that Guan Yu could not take the son of the emperor away even if he called.

However, in the end, it was not necessary for Cao Cao to move the capital, because Guan Yu was killed after crossing the river in Lumeng, who pretended to be ill. In the end, Guan Yu defeated Maicheng and died in the hands of his former ally Sun Wu.
