You can borrow five books at a time for 27 days. If the limit is exceeded, you can ask for an extension (27 days). After that, you will be charged 70 points for each book every day (it seems that I can't remember exactly how many points).
The library card is issued every quarter (3 months) 10 yuan, and you can also deposit money in your card to surf the Internet. The library has a screening room, and there are regular movies or academic gatherings.
