It is said that the loss of Jingzhou was caused by Guan Yu, although he had a large part of the reason in it, but he was inseparable from another person. That was Mi Fang, at the critical moment when Lü Meng sent an army to attack Jingzhou, Mi Fang and Fu Shiren actually chose Kaesong to surrender to Sun Quan, and the naked betrayal of the two of them really dealt Guan Yu a heavy blow, directly leaving him homeless, and finally died tragically under Lü Meng's sword.
To say that Fu Shiren surrendered to Eastern Wu, many people have nothing to say. But Mi Fang is very different, when Liu Bei had nothing, Mi Fang and Mi Zhu brothers donated a lot of money to support Liu Bei to recruit troops to expand their strength, followed Liu Bei for 24 years, in the beginning of the most difficult and difficult days have come, and now Mi Fang has not only become the brother-in-law of Liu Bei, the king of Hanzhong, but also become a Taishou, which can be said to have status and status. But why did he choose to pit Liu Bei at this critical time, causing Liu Bei to lose his troops and lose Jingzhou? There are three main reasons for this:
First, he has always been at odds with Guan Yu. In the Romance of the Three Kingdoms, it is written: "Su Suspect (Guan) Yu is light on himself", "Fang and Ren Xian are afraid and uneasy", that is to say, Guan Yu Su looks down on Mi Fang, although Mi Fang and Liu Bei have a layer of kinship, but we know that Guan Yu has always been arrogant, and few people in the world are really convinced, even Sun Quan sent emissaries to say kiss, the two formed a family of children, were scolded by Guan Yu, enough to see what kind of arrogance Guan Yu was to. Then it is not surprising to despise Mi Fang.
Mi Fang and Fu Shiren had problems with grain and grass many times, and each time Guan Yu severely reprimanded him and said that "he should still be cured." That means, I'll pick you up when I'm back from the battle!" This made Mi Fang and his two people feel afraid, afraid that Guan Yu would find him to settle accounts when the time came, which prompted Mi Fang's idea of rebellion.
Second, he was worried about being disposed of by Liu Bei. Although Mi Fang knew Guan Yu's strength, under the joint siege and suppression of Sun Quan and Cao Cao, he was not so confident in Guan Yu and was worried that Guan Yu would be defeated. However, once Guan Yu failed, he would be afraid that Liu Bei would be punished by Liu Bei, and even thought that he would be killed by Liu Bei. We can see that liu feng was later killed by Liu Bei, he just did not send troops to save Guan Yu, even as Liu Bei's righteous son, he could not escape the fate of being killed in the end. And Mi Fang's worry is also not unreasonable, after all, it has been verified on Liu Feng.
Third, the conditions offered by Eastern Wu are attractive. As a representative of Eastern Wu, Yu Tuan went to lobby Mi Fang and Fu Shiren, explaining to them the punishment that might be meted out to Liu Bei after the war, as well as various conditions unfavorable to them. At the same time, it also promised various benefits after defecting to Eastern Wu, which would not only make them rich and worry-free, but also ensure that their official fortunes were prosperous.
Therefore, after weighing the pros and cons, Mi Fang chose to betray Liu Bei and surrender to Eastern Wu, which not only avoided Liu Bei's possible punishment for him, but also was still heavily used in Eastern Wu, and his treatment did not drop at all compared with before. Later, when he followed He Qi to conquest Puchun, Mi Fang also made a lot of military achievements. However, the life of the seller seeking glory was not good, and Mi Fang would be ridiculed by the Wu people from time to time, especially Yu Tuan, who persuaded him to surrender, and repeatedly insulted him. For all this, Mi Fang can only choose to endure.
