Three cities and I have been to 2 of them. Xiamen is still on my list, if only for the beach I heard so much about.
Xian is probably the most widely known of the three. With it’s Terracotta army it’s one of the main attractions in China. The town itself is pretty nice too. The muslim quarter with the 1250 year old Mosque as well as the nearby city walls.
Kunming is one of my favorite cities. Lived there for a couple of years. It’s laid back, almost slow, has great food and the sun almost always shines.
Xiamen, as said before, I know less about but from the limited available websites I have found until now it should be worth a visit
