Citizens do not have to visit the library in person, nor are they restricted by the opening and closing time of the library. They only need a card to borrow and return books by themselves. Self-service library is located in the east of Children's Library, No.477 Linghu South Road. Swipe your card at the door and press the switch when you go out. In addition, there are six high-definition cameras for indoor and outdoor monitoring. You can borrow three books at a time for 20 days.
