Thank you for your questions about self-study in Shenzhen University City Library (Shenzhen Science and Technology Library)!

You don't need any documents.

There will be more people on weekends, but it won't be said that there is no place.

Security guards will ensure the safety of the university town. Unlike students, they will be asked to show their certificates when they enter the door, and then talk about borrowing books from the library. For your convenience, you can apply for a library card in the library. Now you should borrow two books, the deposit is 100 yuan, and four books are 200 yuan. And so on. You can also surf the Internet for free with your library card. I hope it helps you!
