Are there Qin immigrants in Yongzhou?

I usually read some history books and have a better understanding of history. If I return to the Qin Dynasty, I may become a famous prophet in a short time, and I may be regarded as a master by people at that time. At the same time, I will pass on some modern civilizations to the past, so that history will be remembered in history because of me. I guess my name is in all textbooks now. It's just pure fantasy. Haha.
