Because of Liu Bei's two-sided and three-bladed sword, Liu Zhang, who had originally hoped for the help of his relatives, could only pay the price for his own introduction of wolves into the house. However, at this time, he was already a little disheartened, coupled with the fact that he could not bear to let the lives suffer miserably, so he thought about it and gave Chengdu away. Although he had made meritorious contributions to the city, Liu Bei could not let him stay on this ground.

Of course, Liu Bei always played the role of a righteous gentleman, so he could not kill Liu Zhang, so he had to send him to the distant Jingzhou and let him recuperate there. Because the people at that time, including the courtiers and the people, knew that in this matter, Liu Bei did something very unorthodox. If Liu Zhang was allowed to stay in Yizhou, Liu Bei would definitely not be at ease. So what happened to Liu Zhang and his sons?
Let's take a look at Liu Zhang. Guan Yu, who was guarding Jingzhou, was eventually defeated and killed. In this way, he stayed there and fell into the hands of Sun Quan. Considering that the two sides had already torn their faces, Sun Quan no longer cared about Liu Bei's attitude, so he moved Liu Zhang out as a pawn and appointed him as Yizhou Pastor. Of course, it is impossible to really go to Yizhou, to put it bluntly, Liu Zhang has become a puppet at this time.
However, not long after Liu Zhang arrived at Zigui, he fell ill and whimpered. So after the capture of Yizhou, how did Liu Bei treat Liu Zhang's two sons? In fact, according to Liu Bei's thoughts at that time, he wanted those two people to follow their father to Jingzhou. Liu Bei also wanted to see if he was not upset. However, under Pang Xi's repeated pleading, Liu Bei had no choice but to take care of the face of this old minister in Shu and let Liu Zhang's eldest son Liu Xun stay.
Although Liu Xun was made a general in the fengche, he had no real power at all. For this reason, although he was able to stay, he did not dare to make any noise until he finally fell ill and died. Liu Zhang brought to Jingzhou was his second son Liu Yan. After his father's death, Sun Quan took him out again, let him continue to serve as the so-called puppet Yizhou pastor, and handed over to him the area where the rebellion in South China was "governed", of course, only in name and no power.
After Liu Bei's death, Zhuge Liang chose to re-associate with Eastern Wu. Hindered by Cao Pi's tiger's gaze, Eastern Wu also felt that good cooperation was the only choice for survival at this time, so the alliance between the two families was restored. Coupled with the fact that at this time, the rebellion in Nanzhong had been put down by Zhuge Liang, and the dispensable pseudo-Yizhou Mu had no place to govern.
Rao was so, and Sun Quan refused to let Liu Xian go, took him back to Jianye, and gave him an official position in the imperial history. In fact, this is completely in name only, just to look good on the face. For Liu Yan, no matter what it is, it is better to save his life, so he is also safe and stable, and he can also die well.
