Lin Baixin Zhu Bao Library is a free library. The first and second floors are reading rooms. The first floor is a children's reading room, and the second floor is a larger reading room for all staff. There are more natural books. Reading is free, but it costs money to borrow a library card, but most of the money for the card is a deposit, so you can get it back when you return the card, but remember not to lose the receipt, otherwise you can't return it. There are also two kinds of library cards, actually on the first floor and the second floor. The amount of the deposit depends on how much you intend to borrow at a time.
As for the opening hours, if I remember correctly, it is closed on Monday, and the longest opening time is Saturday. I usually go after nine o'clock in the morning, and then I have already opened the door until nine o'clock at the latest.
