Originally just a place name, it was forcibly changed to Jiankang by the emperor. What's the secret behind it?

At that time, the place name of that place was Jianye, and Sima Ye changed the place name to Jiankang for the following reasons.

First of all, the place name at that time was Jianye, and his name was Sima Ye. He changed his name to avoid taboo. There were many examples of taboos at that time. As an emperor, I feel that I can't share the same name and surname, and I can't repeat any word. Because they feel unique, they are chosen by nature, and there can be no people like them in the world. They are unique, and neither place names nor names can be the same as them. So when he became emperor, he decided to change the place name and the words that repeated his name.

Secondly, they have the final say in changing the name, which is more casual. He is the emperor, the statue of the Ninth Five-Year Plan, and their power is relatively large. They can do everything by themselves, and no one can restrain them. Even if someone will give them advice, it is up to them to decide whether to adopt the ministers' suggestions in the end.

Finally, it may be because Sima Ye was happy when he succeeded to the throne, because he had become an emperor, so he felt the need for a new look, so he started with changing the place name. At that time, Jianye was just a duplicate name, so the place name of this place was changed to another name. The change of place name was only a small move for the emperor, but it actually had no effect on him.

In short, the main reason for changing the place name may be that it is a bit repetitive with your own name and needs to be avoided, so you changed the place name at that time.
