I maintain that Liu Chan is a very smart person. If you don’t believe this, you can compare the endings of the Wei, Shu and Wu Three Kingdoms. If Liu Chan is said to be stupid, then Liu Bei, who is the most accurate judge of people, does not only have one son but only made him the prince. Liu Bei's selection of talents was appropriate and precise. How could he be wrong about his own son?

But despite this, Liu Chan's sentence "I am happy here, but I don't miss Shu" has been passed down through the ages as a less promising sentence. He did not intend to return to Shu and left such an eternal saying. Everyone said that he was a fool. But if you assume that if he said "I want to restore the country", Sima Zhao would behead him. According to the version passed down, people would think that he was ignorant of current affairs. I would say that Liu Chan is still smart. He knew that he had to pretend to be stupid in front of Sima Zhao. Isn't this the same as being wise and foolish?

In fact, the real fool was Sima Zhao. He did not see that Liu Chan was pretending to be stupid. Instead, he cursed in his heart: "What a fool! He is an Adou who cannot be helped!" He said: "I No more worries!" No longer on guard against Liu Chan. The smoke bomb Liu Chan put up hid Sima's knowledge and misled future generations, who thought he was stupid. It seems unbelievable that Sima Zhao died laughing, but actually it makes sense if you study it carefully. Sima Zhao was still fighting for years at such an old age. While fighting, he had to pay attention to the underground workers of the restoration team around him. The work pressure was definitely not small. He was amused by Liu Chan's different thoughts and was still in a situation like Shu. He secreted substances like adrenaline. It is not impossible to cause blood vessel rupture and eventual death from cerebral hemorrhage.

There is a folk saying that Sima Zhao laughed so hard that he had a stroke and died. However, he was happy to forget about Shu and acted foolishly, but he was just acting for the occasion.
