Because parents work hard to earn money, basically everything can be said to be for their children. If you leave your child at home, it will do great psychological harm to the child, and the child will feel that he is not liked by you, or that his thoughts and other aspects are not taken care of by you. In addition, the elderly's intergenerational education for their children is not as effective as that of their parents, and their thoughts can't keep up with the times and they can't guide their children well. So I think it's best to have children around.
