Dear schoolmates,
Our school is trying to be a better place for all. We know good manners are really important. And we can do something together.
In order to make our school more beautiful, we should keep our classrooms clean every day. Remember not to drop litter everywhere. And we should remember not to laugh or talk loudly in public places. When we are in the library, we must keep quiet. It's also important to follow school rules and queue for everything. We should always behave politely and help each other.
Good manners make our school better. Let's start from ourselves!
