The library can borrow eight books at a time and return them one month later. After a month, if you haven't finished reading these eight books, you can renew them.

If you renew the fee, you can renew it online or leave a message by phone for one month. If it exceeds this month, you have to pay it back. But if you haven't finished reading it now, you can still watch it for a few more months, as long as you return it.
