I know different signs mean different things. There's a sign near

the bookshelves. It tells that people should keep quiet in the library. So we shouldn't shout or talk loudly

there. There are some signs on the wall. They mean "No eating or drinking" and "No smoking". There's

a sign on the bin. It says "No littering". We should put rubbish in the bin. Everyone should follow the signs

to keep the library clean and tidy.
