documents: #Person1#: You know that in China all the children should go to school and must finish the primary and junior school. It's the law.
  #Person2#: Yes, I know this quite well. But still there are some children who can't go to school because of their poverty.
  #Person1#: Yes, it's a matter of money. You see, education here is not completely free for the students. If it were so it would cost the government too much money.
  #Person2#: Do all parents send their children to state schools?
  #Person1#: Yes, nearly all of them. If you are rich, you may prefer to send your children to private schools, but it takes a lot of money.
