What are the "stupid" emperors in history?

As a history lover, I have something to say. Due to the revision of history books and the processing of folk art, the image of Liu Chan, the late ruler of Shu-Han Dynasty, makes people feel a little "stupid". If we clear the fog of history, we will find that Liu Chan is not as stupid as people say.

Many film and television images regard Liu Chan as a bad king, and the historical books of past dynasties have a low evaluation of Liu Chan. However, the master did not think that Liu Chan was a "stupid" emperor. Under the background of that era, Liu Chan, as the Emperor of Shu Han, was not so miserable.

Since Zhuge Liang's death, Liu Chan has been in charge of Shu for nearly thirty years. During these 30 years, Shu Han, as the poorest and weakest country in the three countries, was relatively stable and there was no major civil strife. On the other hand, in Wei and Wu, local rebellions and court coups occurred frequently, and the emperor was abolished or became a puppet. Liu Chan of Shu Han successfully took over the political power after Zhuge Liang's death and remained in power until Shu Han's death. This is not something that a "stupid" emperor like Jin Huidi can do.

In dealing with the relationship with ministers, Liu Chan's method is also very clever. Jiang Wei asked the eunuch Huang Hao to be executed. This is a problem for Liu Chan, because if Jiang Wei's request is granted, it is hard to say that Jiang Wei will push his luck and his authority will be affected. If you don't agree, it may lead to the chilling of Jiang Wei and others, which will make people feel close to the villain. Between the dilemma, Liu Chan took a way. He told Jiang Wei that Huang Hao was a mean person and he hated him, so Jiang Wei didn't care. And let Huang Hao apologize to Jiang Wei, who was afraid that Huang Hao was powerful and the matter would go away. Later, Jiang Wei devoted himself to Shu Han, and the demise of Shu Han also devoted himself to Shu, and never left Germany with Liu Chan. This is something few emperors can do.

After surrendering to Wei, I was so happy that I gave up my doubts. For Liu Chan at that time, it was the best way to protect himself and the people around him. You can refer to the fate of the last two emperors in the Western Jin Dynasty and Li Houzhu in the Southern Tang Dynasty. For the emperor, how can there be no pain of national subjugation? However, there is no hope and no way to restore the country. Different people have different opinions. Maybe someone will ask Liu Chan why he didn't die. This is a personal choice. Almost all the kings who perished at the same time surrendered to the new dynasty.

By the way, the answer says that Liu Chan is not a good emperor. During his reign, he was close to villains, built large-scale projects, exploited the people, surrendered to Wei and destroyed Shu Han. However, according to the answer, Liu Chan is the cleverest of the subjugated kings.
