Two things can make ordinary people become polite. One is about the family education. Another has got to do something with school education in my mind. On one hand, children might learn something one or two from their parents` behaviors and words, children could be definitely affected by good examples of their life, apparently, parents are the ones who are right for this. On the other hand, school is another place to make people become polite. The school`s education is playing an important role in this trend. Teachers would eventually show something one or two on politeness to their students. So, I think that the education of school and personal family could be the key point. They are equally important. That is it.
