Dear Lucy,

Last time you said you wanted to borrowed some books from our library and asked me about the library rules and regulations. Now I'd like to tell you something about it in detail.
First, our school library is open everyday, but it's not allowed to eat at the library.
Second, each person can borrow two books per time at the most, and you can keep the books for two weeks.
Third, you must return the books on time, otherwise you may get a fine of two yuan per day for one book.
Last but not least, everyone should take good care the books, no scribbling or graffiti.
Let's go to the library next time, OK?

Yours,
Li Nan
