How old are late marriage, early marriage, middle age and old age?

China's marriage law stipulates that the age of marriage should not be earlier than 22 for men and 20 for women. Late marriage and childbearing should be encouraged. The so-called "late marriage" means that men are over 25 years old and women are over 23 years old. The so-called "late childbearing" means that women give birth to their first child after the age of 24. Late marriage and late childbearing are encouraged by China's marriage law and are also China's current family planning policy.

Generally speaking, the ancients divided people's life in this way: those whose childhood is below 12 years old and above 12 years old are called juvenile total angle age. The 20-year-old weak crown is youth. Some people think that after 18, 0.30 represents youth, entering middle age, and 0.50 is called a mature fate. Of course, it is old. Early years refer to adolescence, corresponding to the age before 16 and 16~3 1, middle age corresponds to the age before 48, and old age corresponds to the age after 60.
