Failure in educating children is the biggest regret of parents' life. No matter how beautiful your house is, no matter how rich you are, if you fail in educating your children, your life will also fail. If you don't make too much money in this life, there is no such thing as success. But if you successfully educate your children, your life is also successful. Therefore, success in educating children equals success in life, and failure in educating children equals irreparable regret in life.
