Nowadays, more and more people realized the importance of education. Many parents think they must let their children win at the starting line, if they want their children be successful in the future. So they will add a lot of extra classes (Olympic classes, English classes, composition classes, dancing classes, violin classes and so on) to their children form Grade one, or even earlier. On the other hand, some parents don’t think losing at the starting line is so serious. They want their children to have a happy childhood.
