Are there any interesting unpopular cities in China?

Eastern Jilin. Mainly distributed in Changbai Mountain area of Yanbian Prefecture. Now the heat is unbearable, and the advertisement of CCTV Jilin Province has played the slogan of "22 degrees of summer in Jilin". I think Jilin people are a little modest. At least as far as Yanbian Prefecture is concerned, 22 degrees may be their highest temperature. It's still quite cold in the morning and evening, and it's cool during the day. The forest is covered here, there are many rivers, and there are many kinds of wild animals and plants, which are delicious. For example, Dunhua in Jilin, Yanji in Jilin, Hunchun in Jilin and Tonghua in Jilin are all very suitable for holiday travel. The climate, scenery and food are all good. This is also my hometown. I have been to so many places, and I don't feel much better than my hometown.
