Of course, some parents let their children learn this and that out of selfishness. For example, this parent once had a dream, but later he couldn't realize it himself and passed it on to his children. You see, interest classes are everywhere now, because the market is huge. A kindergarten child can't wait to have a full curriculum during the weekend holiday, such as piano class, Lego class, chess class and drawing class. Watching, everyone feels tired for these children, but some parents think that others can learn and their families can't fall behind.
If others learn a lot and children don't learn much, parents will also have an inexplicable anxiety, such as children will be left behind by their peers. Therefore, a happy childhood is really a scarce product for children. It is the parents' wish that their children attend some endless cram schools.
Some parents are purely for their vanity and can't compare with other children. There are all kinds of comparisons, so-called paying for education, parents are willing.
To sum up, one of the reasons for this situation is that they want their children to have a good future. How fierce the social competition is now, perhaps because of the vanity of comparison, some parents really care about their face. People in China also attach great importance to children's education, so spending money and effort in this respect is all one heart and painless. I would rather suffer myself than let my children lose a little in education.
