There is no charge for self-study. If you want to borrow books, you need a card. You need an ID card or household registration book on the first floor. You don't need to borrow a card for self-study On the second and fourth floors, you are the study rooms. Books are not allowed to be brought in the reading place, but schoolbags can be stored. However, this is a festival. I didn't open it yesterday, so I don't know today You can go to the website of Dalian Development Zone Library for details, hoping to help you.
