This is Zhou Yu's plan to recruit Liu Bei as his son-in-law and lure Liu Bei to Nanxu to rob Jingzhou. In fact, this plan is not very clever. When Lv Fan represented Sun Quan, Zhuge Liang knew that "this was Zhou Yu's plan", so he thought about countermeasures. It's important to send an effective bodyguard. In terms of martial arts, Guan Yu, Zhang Fei, Zhao Yun and Huang Zhong are all competent, but this candidate was decided by Zhuge Liang after careful consideration.
Guan Yu is Liu Bei's sworn brother and has been following Liu Bei for a long time. He is the second person in Liu Bei Group after him. Although Zhuge Liang has come out of the mountain at this time and usually assists Liu Bei in handling affairs, it is obvious that the military still depends on Guan Yu, so let him continue to guard Jingzhou.
Zhang is brave, the image of the question is too fierce, and it is easy to scare the other side. Moreover, Zhang Fei has a bad temper. If a fire breaks out and people are hurt, that's not good. After all, Liu Bei went to get married, not to fight.
Huang Zhong's problem is that he is too old and Liu Bei is not young. With a veteran, people feel that Liu Bei Group is a little late. Moreover, although Huang Zhong has excellent force, his reputation is not as good as that of Guan Yu, Zhang Fei and Zhao Yun, and his deterrence is insufficient. Sun Liu and his family still need to help each other against Cao Cao. It is the best choice to frighten each other without starting a fight, so as not to make enemies.
Compared with Zhao Yun, martial arts is absolutely no problem; Secondly, he is steady, wise and brave; Thirdly, he is handsome and full of heroic spirit, which makes people feel very comfortable; Fourth, after the First World War in Changbanpo, Zhao Yun also made a name for himself. Emma Wu Guotai knows that it is better to prevent villains than to prevent villains; Fifth, Zhao Yun was responsible for protecting Liu Bei's family when he was in Changbanpo. Obviously, this bodyguard's job is also used to it.
So on the whole, Zhao Yun is obviously the most suitable candidate.
