Dear Mayor ，
I am Yang Lin , a senior high school student who moved to this city three months ago. I am writing to draw your attention to some improper behavior among us citizens: littering, scribbling, disobeying the traffic rules and so on.
Such behavior makes our city dirty and unpleasant, and does harm to the image of our city. I always feel ashamed whenever I see this . It is clearly not appropriate for a citizen to litter and scribble about.
I wonder if the city government could place more dustbins around and set up some rules against such behavior. At the same time, people should be encouraged to develop good habits and better behave themselves. I believe that, with the joint efforts of both you and us, our city will become a more enjoyable place in the near future.
Thank you for your consideration.
Yours faithfully,
Yang Lin
