Obviously, this is not going to happen here. In china, there is wide-spread belief that you must treat your parents with respect no matter how awful they might be. If parents treat their kids properly and do their job right then kids will want to visit and help them.
If their parents have taken care of them and been good parents then they should be their for them. Not all parents have been good and usually if they aren't being visited there is usually a good reason for that.
This country can't even get all parents to be involved in their own kids lives there is no way they could pull this off. There shouldn't have to be laws for this crap it should be common decency to respect your parents assuming they treate you right as a child
