Last vacation,i had a trip with my family in Beijing.When i was traveling around the city park,i saw somebody smoking and somebody talking loudly.It really made me feel uncomfortable.And i think it's impolite to talking aloud or smoking in public places.Then i walked to the men and said politely:"Excuse me,would you mind not smoking there?”The man felt sorry and said sorry to us.I really wished that there would not be people smoking in public soon.
