First of all, make sure you are over seventeen. Bring your personal ID card or household registration book and apply for a library card at the entrance counter of adult library of Jiading Library. Each person is limited to one, and the deposit is 100 yuan. Report the loss, pay the 20 yuan fee once, and make up the card for free. If you get it on the spot, you can borrow 6 books from the library on the first floor for each card.
