1. North Bookstore: There are two stores, one in the Bureau of Retired Veteran Cadres and the other opposite Jinhua, Shanghai Road. Among them, the Jinhua study room in Shanghai Road, opposite the North Book City, is bigger and the administrators are more responsible. For people with average economic conditions, this is a good choice, because the fees here are relatively low, and only 30 yuan and 80 yuan are needed in one quarter.

2. Heping Road Qing Ji Library: The environment is good, with two floors, but it may be crowded in winter and summer vacations. The library charges 40 yuan a monthly fee, once a day, and goes to 2 yuan every time.

3. Railway Library: It is air-conditioned and provides study rooms of various grades, including expensive large rooms and small study rooms.

About Liao km's library, you need to swipe your card to enter. I suggest you enter the 1 building from the west gate (the building on the north side). The environment here is relatively good, and the students who take the postgraduate entrance examination are relatively quiet. As for how to draw the card and the specific opening hours, you may need to consult the relevant personnel of the library or the relevant regulations of the school.
