Shanghai, Qingdao and Xiamen, which is the most interesting place to travel in July?

I have been to Xiamen and Shanghai, both during the summer holidays in July and August. I really want to go to Qingdao myself, and I always look at different travel strategies.

Actually, how can I put it? The three cities feel different. First of all, Shanghai is a metropolis and international. If you like the feeling of the city, there is no doubt about Shanghai.

Xiamen belongs to the type of petty bourgeoisie with literary style. Take photos, spend a day in Gulangyu, take photos and eat snacks.

Although Qingdao has never been there, it has coastal cities, beaches and European and American architectural styles. The most important thing is to see which type you like.
