Martial ShengGuan Yu, after accidentally losing Jingzhou in 220 AD, was killed by Soochow , and gave his head to Cao Cao, hoping that the disaster would be diverted to the east, and a generation of famous generals would be offline. Generally speaking, Guan Yu's defeat was mainly due to his own pride. In fact, this is only one aspect. The most important reason lies in Zhuge Liang .

Zhuge Liang's " Longzhong vs. " has always been one of his great brilliance. Although it predicted a divided world and actively helped the future development of Liu Bei , it was also a huge mistake. That is to let Liu Bei divide his troops. If Liu Bei's small family fortune is divided into three parts: Guan Yu, Liu Bei, and Zhuge Liang, how can he compete with the powerful Cao Cao?

After Guan Yu garrisoned Jingzhou, the Shu Han's military strength at that time was completely unable to compete with Cao Cao. It can only be garrisoned. Although Zhuge Liang's strategy allowed the Shu Han to obtain a large area of ​​land, garrisoning like this cannot protect it for a long time. Not to mention taking the initiative to attack, it is completely unable to compete with Cao Cao's main army, so it has always been allied with Wu to resist Cao.

But Zhuge Liang's decision was to obtain Jingzhou, and then Guanzhong troops would be sent out to form a pincer offensive to attack Cao Wei . But Cao Cao himself was not worried because he also knew that Shu Han did not have the strength to attack him. And the facts prove this. Cao Cao's general Xu Huang ran in front of Guan Yu. Guan Yu could only watch helplessly. The troops in his hands were simply not enough to attack the opponent.

Although Guan Yu failed, he had his own pride and disdain for the entire Soochow, coupled with Lu Meng 's sneak attack by White Clothes Crossing the River , and the failure of the battle with Xu Huang in the early war and other reasons. But the most fundamental thing is the lack of its own troops, which is Zhuge Liang's strategic deployment. That is to say, the Shu Han itself belongs to the weak side, but they still disperse their troops to attack the strong side, which is completely self-destructive.

Liu Bei also felt something was wrong at the beginning, and he promised Soochow at the beginning that he would return Jingzhou after getting Liangzhou . In fact, Liu Bei's initial plan was to concentrate his forces to attack Longyou, Cao Wei's weak area. Moreover, Zhuge Liang also attacked here during his several northern expeditions to Cao Wei in the later period. It can be seen that the decision to attack here was everyone's consensus. However, Zhuge Liang's misjudgment in the early stage and his underestimation of his own strength led to Zhuge Liang's reputation for skillfully borrowing Jingzhou and never returning it, but it eventually led to the loss of Guan Yu. After that, there was a series of chain reactions. Zhang Fei was killed. Liu Bei used all the belongings he had accumulated for several years to attack Soochow. As a result, the entire camp was burned down and he himself died of illness in Baidi City. The Shu Han was greatly weakened, and many years later, it started the Northern Expedition again.

Zhuge Liang is a great man. He made outstanding contributions in running the Shu Han and helping the development of the Shu Han. In the beginning, it helped Liu Bei have the capital to compete for the world. However, one mistake ruined the great prospects and even affected the main strategy of uniting Wu to fight against Cao. No one can make mistakes without being a sage, and people’s ideas also undergo significant changes at different stages. There are also great differences between Zhuge Liang in his youth and Zhuge Liang in his later years.

For example, at the beginning, Zhuge Liang appeared in a feather fan and silk scarf, his oars and oars were wiped out in ashes while talking and laughing, and he was extremely confident. But in the later period, Zhuge Liang lost that calmness and had more important responsibilities on his shoulders. Although history does not allow for assumptions, if Zhuge Liang had not made such a decision at the time, it is very likely that the Han Dynasty would be restored, and there would be no idiom about being happy to miss Shu. It may be that he is happy to miss Wei, or he is happy to miss Wu.
