It’s not allowed to throw litter anywhere in the public places. Everyone should obey the rules. Speaking loudly in the reading room is seemed to be very rude. Remember not to do anything that might make other people uncomfortable. We should stand in line when we are waiting for the bus. Try hard to give up the bad habits and develop good ones. We should respect the senior people and talk to them politely. Especially, we should give our seat to old people or women with babies on the bus. I think helping others can not only make us happy but also help us get more experience in life. Please cherish the public property.
