I went there last August. You don't need a self-study certificate, but you have to pay fifty cents. Turning on the air conditioner in summer seems like 1.5 yuan.

There is a study room on the east side of the second, third and fourth floors. Half of the area on the second floor is used to read magazines and newspapers, but I can't remember the specific location of the fifth floor. I didn't close the door until after eight in the evening.

The study room is divided into adult students. Remember to go early to avoid having no seats.
