Marriage is the main switch of family and society, and it is the cornerstone of children's growth and success. Marriage will involve many issues such as economy and personnel. After marriage, it will involve the main responsibility of family planning and raising children's adults. A good marriage needs careful design, starting from reality, making adjustments according to personal identity, and also preventing marriage from losing its mind and degrading its social functions due to economic and opportunity problems, leading to the deterioration of children's genetic personality.
