the more successful the kid is, the less help

he/she can be to the parents. As we all were smart kids and good students, so we can come to foreign country to study or work, so we can not help our parents. Think about those of your classmates who are not so academically achieved, they might stay in china.
Nowadays, I see all Chinese parents send their kids to study pianos, ballets, encourage them to get scholarships, the better the kids are, the less they can care about us, not they don't want to.
