I lived in Europe for a couple of years before I moved to US.
No need to call me 前辈. You do not call a person in 30s 前辈. I just know a little.
I spent some time to study the Roman history and my favorite topic is the French history around the revolution.
Have you learned Latin before? I hope I know that. This is a very helpful language if one travels in Europe.
So you are in Europe for business or your own study? Europe is a wonderful place for sight-seeing, so rich in cultures.
