If you want to study by yourself with your bag, you can do it on the third and fourth floors. Among them, you can enter the third floor without a library card. The environment is good and there are not many people. It was 9 am to 8 pm or 9 pm.
You need a library card to enter the fourth floor. There are fewer people, the table is wider, in short, the environment is very good, there are independent glass compartments, but that seems to require an appointment. The fourth floor is open until 5 pm.
There are sockets and wifi on the third and fourth floors.
If you want to apply for a library card, just bring your ID card, and you need to pay a deposit of 100, which will be returned to you when you return the card.
