The ancient city is quiet, no need to buy tickets, but you have to scan the security code and wear a mask. It is suitable for people who have cultural heritage to see it, otherwise they can only be used as an Internet celebrity attraction to punch in and take pictures. When you enter the door, you can see many interesting words written on the wall. The middle is Fang Guoyu's learning experience. Inside is the residential area study hall hall patio. There are many wonderful things and other tourists to experience.
