You'd better get a library card for the public library yourself. Superstar mobile library can log in not only with the library card of university library, but also with the library card of public library. For example, I use the library card of Hunan Library for two years 100 yuan. The initial password is the cardholder's birthday (eight digits). So you can borrow a card from the public library with your ID card, and then log in to the mobile library with the account on the card. Most of the books in it can be downloaded.
