Should children care about their parents' lifestyle? If you care, how do you care?

Of course, children have to take care of their parents, and even knowing that it is a quagmire can't help her. But we really can't control their parents' affairs, so we can only gently persuade them. If they don't listen, they can do nothing. Now that you have grown up, your parents can really live their own lives. If you really can't persuade them, you can only make the worst plan and give them some money to support the elderly in the future. Don't mind other things, and don't be like your parents.
