In the Three Kingdoms period, fighting can be said to be commonplace, and people in that era were also accustomed to a life of displacement due to fighting. There are no victorious generals in the world, even If it is Lü Bu and Guan Yu, who are full of prestige, they will also be reduced to defeated generals under others. So in those days, failure was not a shameful thing.
Guan Yu was captured by Cao Cao
During the Three Kingdoms period, Wei Shu and Wu stood on three feet. The leaders of the Three Kingdoms, Cao Cao, Liu Bei, and Sun Quan, were all thirsty for talents, and for real talents, even if they lowered their posture, they had to take them under their command, just as Liu Bei once went to Ask Zhuge Liang to come out of the mountain. And there were also many very strong people in that era, but they were defeated due to other factors. Therefore, they will not kill all the generals who surrender, and they will even set up a feast, hoping to keep them.
Guan Yu is an example, when he was captured by Cao Cao, Cao Cao not only did not abuse him, but also put on a banquet and sent beautiful women to entertain him, which shows that they all love talent. Looking at the entire Three Kingdoms, there were many generals who surrendered, most of whom were not mistreated, but there was such a person, but everyone could not tolerate it, and this person was Forbidden. It is also unlucky to say that it comes from the prohibition. At that time, Yu Ban was a defeated general under Guan Yu, and in order to save his life, he surrendered to Guan Yu, and Guan Yu's lord was Liu Bei, which also meant that he became Liu Bei's subordinate.
The end of the forbidden
However, Guan Yu then carelessly lost Jingzhou and lost his life, and Yu Ban did not know Liu Bei, at this time his situation was very embarrassing, from Guan Yu's captive to Sun Quan's prisoner. Together with Guan Yu, he was crushed into Sun Quan's hands. Because Yu Ban was Cao Cao's soldier, out of pity, Sun Quan thought about letting him go back, because Sun Quan did not intend to reuse him. If Yu Ban had been released at this time, his end might not have been so tragic, and Cao Cao, out of guilt, might have let him return to his hometown for the elderly. However, Sun Quan has been detaining Yu Ban and has not taken any other action.
After Cao Pi succeeded to the throne, Sun Quan released Yu Ban back, but Cao Pi did not have much deep friendship with Yu Ban, and Yu Ban was just a traitor to him who surrendered to the enemy country. Moreover, Cao Pi had just ascended to the throne, and it was precisely the time to kill the chicken and the monkey. If the minister of the DPRK saw that a traitor could still enjoy good treatment when he returned home, he was afraid that the army would be unstable, so he took the knife and gave him death. It's just that poor Yu Forbidden was kicked around like a ball, and in the end he was not able to enjoy his old age. This can only be blamed on the bad luck of the forbidden, after all, he is also involuntary.
