There seems to be no serious snack street. Pick two places where snacks are concentrated and recommend them to you.
1. Take the No.9 bus from Lvyuan, get off at Erxianju Station and look across the road, and you will see it.
2. There are many students and many kinds of snacks in Taoli Street. Take the No.9 bus from the Travel Institute, get off at Garden Hotel Station, change to No.6 and No.26, get off at Taoli Street and stroll inside. Actually, it's not far to get off at No.9, but it's the first time to go there, so change to the next bus.
Chengde City Library is located at Xidajiekou, opposite Gejiahutong. It was visited two years ago, and the first floor is full of Internet cafes. From the appearance, it is dilapidated. I feel that it has existed in name only, and it is not worth going there ~ It is said that the library of Medical College is very large and has comprehensive books, so you can contact to see if there are any students there and help me get a library card.
There are many video shops in Taoli Street, but not many in other places. Get off at Erxianju Station, which I first mentioned, cross the bridge across the street, go straight ahead, and you can see one on your left.
