Our city hopes to keep the Civilized City. We know it includes good behavior and excellent environment. So I want everyone can do something for it. To good behavior, we should be friendly to others, talk with others politely and help people in trouble. Please don't break the traffic rules or talk loudly in public. To excellent environment, I think we can plant trees, pick up the litter and clean the small ads on the wall. You'd better not waste water or walk on the grassland.
