I have never been to Xi 'an. I have been to the provincial map next to the provincial body. Just entering the door, you can't bring your schoolbag, you don't have to pay, there are quite a lot of people on weekends, and there are still empty seats. There are many places to eat around, such as expensive storefronts and pancake fruit carts, just outside the east gate of the province. I don't remember the closing time, the environment is ok, quiet and clean, and the equipment doesn't know what you asked. There are desks and chairs, hehe. There is a toilet.
