How about the library card of Guangzhou Children's Library?

To apply for a library card, you need to pay a deposit ranging from 100 to 600 yuan. If you pay a deposit of 100 yuan, you can borrow books within 100 yuan, and so on. Officially, the opening hours are: 9:00- 19:00 every day (closed on Thursday afternoon for housekeeping), and the opening hours on legal holidays are adjusted to 9:00- 17:00.
