Apply for a library card at the entrance of the borrowing hall on the first floor of Shijingshan Library, then enter the borrowing hall on the first floor, walk to the right, swipe your card, borrow books indefinitely (just before closing), and return to the place where you came in after borrowing. Go out in another direction this time, swipe your card first, and wait for the staff to sweep the book. After that, there will be a machine to print the loan book list, just take it down and go with the book, without swiping the card. The loan period is 2 weeks. You can call the number on the loan slip and renew it for two weeks.
Now the study room is free, so you don't have to buy a ticket.
