Many people think that if Guan Yu fails and Liu Feng leads many people to help Guan Yu, Guan Yu will surely turn defeat into victory. Actually, this is not very reliable. Needless to say, Liu Feng and Meng Da, who were stationed in the army at that time, were at odds. Shang Yong has just joined Shu Han, and his heart is unstable, but he needs the army to maintain public order. Liu Feng can divide no more than five or six thousand troops, so it is undoubtedly necessary to take these people to help Guan Yu.
Guan Yu's failure led to the decline of Han Shu Group, because once Guan Yu failed, Jingzhou fell into the hands of Wu Dong and Cao Wei. Since then, Liu Bei Group has been unable to get their hands on the Central Plains, so Zhuge Liang told Guan Yu not to attack alone a long time ago. If he attacks alone, Wu Dong will inevitably cause trouble. After the battle with Cao Cao became more and more smooth, he gradually became arrogant and forgot Zhuge Liang's words, which led to being attacked by Wu Dong and losing Jingzhou.
Guan Yu called for help at that time. Not far from him, Liu Bei's adopted sons Liu Feng and Meng Da are stationed in Shang Yong, which is a neglected place. There are mountains on both sides of this place. Although there are trails, they are extremely dangerous. Backed by Hanzhong, we can only go south to take the land of Xinye and Wancheng, which can be said to be a springboard for attack.
Liu Feng didn't help Guan Yu, not because he didn't want to, but because he went, there was nothing he could do. He has more than 10,000 soldiers and horses under his command, but he wants to share them equally with Mengda. On the one hand, he maintains public order, on the other hand, he is on guard against Cao Cao. There were a lot of military forces in Wancheng at that time. If Liu Feng changes slightly, Cao Cao will protect himself in this area of Wancheng and stop Liu Feng in this area, so even if Liu Feng desperately helps Guan Yu, he will.
