Who is the "stupid emperor" in history?

About Sima Dezong's physiological state, all kinds of historical records are exactly the same. "The Book of Jin Andy Ji" said that "the emperor is not beneficial, long and short, and it is unspeakable. Although the summer and winter have changed, it is indisputable. Nothing that stops is their own "; "Zi Tong Zhi Jian" said, "Andy is too young to speak. As for cold and summer hunger, he can't tell, eating and sleeping are not his own "; "Continued Jinyang Autumn" said that "Huang An is not wise and can't help himself. (Gong) Every time the emperor waited, the news came that he was hungry and cold, but he was humbly prepared. " Growing up, Emperor Jin 'an couldn't speak, didn't know how hungry he was, didn't suffer from cold or heat, couldn't take care of himself by eating and drinking Lazarus, and relied on others to take care of everything. This kind of "idiot emperor" in the true sense is a unique example among emperors in past dynasties.

Emperor Jin's congenital idiot can be said to be caused by his father Jin Xiaodi Sima Yao's long-term drinking. Modern medicine has proved that alcohol can affect sperm activity, reduce sperm quality and cause sperm malformation, which has great destructive power to germ cells and embryo development, and even give birth to deformed people in severe cases. Regardless of Sima Yao's drinking, "Indulge in debauchery, almost all night long, and rarely wake up", and often "indulge in worship, fly thousands of times in the long night" (Book of Jin), "indulge in drinking, linger in the inner temple, wake up to cure diseases, which is rare for outsiders" (Zi Tongzhi Jian). Under the influence of alcohol for many years, Sima Yao's fertility declined seriously, not only giving birth to fewer children, but also giving birth to an idiot son Sima Dezong with super mental retardation.
