The well-known "Romance of the Three Kingdoms" says that Guan Yu was "in Cao's camp and his heart is in Han", but there is another person who really sums up the meaning of this sentence, and that is Xu Shu.

Everyone knows what this sentence means, that is, no matter what kind of environment I am in, I want to help someone, but my heart is not here. Because of many unexplainable reasons, Xu Shu had to betray the person he followed before, Liu Bei, and surrendered to Cao Cao. But as for him, in order to repay Liu Bei's appreciation and promotion of him, he did not care about his own The master, Cao Cao, has never had any thoughts about Liu Bei in his whole life. He can be said to be a very conscientious person.

In fact, in "The Romance of the Three Kingdoms", why did Xu Shu surrender to Cao Cao? This involves a historical allusion, Xu Shu entered Cao Ying without saying a word. Xu Shu was a very ambitious man. He initially changed his name and defected to Liu Bei and became his military advisor, making suggestions and winning two battles. Not long after he was happy, the other party arrested his mother, and he had no choice but to go to Cao Ying.

However, his mother was not actually captured, but was captured while chasing Liu Bei. Moreover, the overall strength of the troops led by Liu Bei at that time was too weak, so Xu Shu thought twice about it. He bid farewell to Liu Bei and submitted to Cao Cao. The reason for trying so hard to win over Xu Shu is because he is a talent, and the counselors around Cao Cao think he is very powerful, so this person must be roped into his camp, regardless of whether he is willing or not.

In fact, Cao Cao loves talents very well, but he should be persuaded in another way. However, it is precisely because of Cao Cao's actions that the eternal saying "Being in Cao Cao's camp and being in Han" has been spread. to date.
