The big joke in history: after he took over the throne of his grandson, he still respected his grandson as the emperor's father. Which emperor is this?

The emperor is Sima Lun. Sima Yi actually had nine children in history, and Sima Lun was the youngest of the nine children, who was born to Sima Yi by a concubine. Because Sima Yi has too many children, not every child is well disciplined. Sima Lun grew up to be a wretched and incompetent gentleman.

When Sima Lun was the king of Langya County, he had already done a very ridiculous thing. After Sima Yi's death, Sima Yan seized power and usurped the throne, established the State of Jin, became emperor, and made his uncle Sima Lun king of Langya County, but Sima Lun was not satisfied with this, and wanted to steal Sima Yan's royal fur. Unfortunately, someone happened to bump into me. So Sima Lun was impeached by his ministers and should have been sentenced to death, but Sima Yan was soft-hearted, leaving him alone, and Sima Lun was safe and sound.

Sima Lun thinks he is very talented, and he is not satisfied with it. After Sima Yan's death, Sima Zhong succeeded to the throne, but he was mentally retarded, so it was actually his queen Jia Nanfeng who took power in the State of Jin. Sima Lun was the prince who was a teacher at that time, and he was always unwilling. He thought he was an artist, so Sima Lun made up his mind and began to spare no effort to please Jia Nanfeng and flatter Jia Nanfeng. Of course, this is not invalid. Jia Nanfeng really trusts Sima Lun more and more.

Sima Lun launched a mutiny and attempted to usurp the throne. Jia Nanfeng designed to depose the prince because he was not his real mother, and conspired with Sima Lun to kill him. Sima Lun thought it was time to launch a mutiny, abolish Queen Jia Nanfeng, destroy the etiquette of princelings and seize the power of the imperial court. Then he used public opinion to become emperor, perhaps because he felt sorry for himself, so he made his nephew Sima Zhong the emperor's father.
