Which city is more suitable for studying abroad, Nice, Lyon, Montpellier, clermont-ferrand, Lille and Metz?

I personally recommend Labyrinth and Moby to cheat the old university town. The atmosphere is very good, and the public security in the south of France is also good. The transportation is convenient and life is good, but there are many people in China and the teachers are not very friendly. The maze is also awesome. Not many people, at least there are many people in China. Life is comfortable and quiet, suitable for study. Teachers and classmates are very good, and life is convenient. Although it is not as cool as a tram, the city is not very big, and it is comfortable to walk when you are free. Besides, Maze is very convenient to Luxembourg. The train from Luxembourg to neighboring countries is cheap and the trip is good, but it will be quite cold in winter, at least I don't think it can stand it. ), in short, the maze is the favorite of many French cities I have been to, a little more than deception! Lyon is a bit big, although everything is convenient, but the public security corner in big cities is relatively large, but life is meaningless. Lyon and Claremont are both in central France, with distinct seasons and good weather. Lille is far away in the north, and it is certain that it is cold in winter (in fact, cold is not a problem, but heavy snow is the big problem). Go and play in Nice.
