2. Welfare mechanism. Because the welfare mechanism in China is not as good as that in foreign countries, parents may need the support of their children to continue their lives when they are old. For example, in some foreign countries with low birth rates, the state welfare subsidies are too high, resulting in no children to support and not enough money to support the elderly. Unlike China, China doesn't have such high welfare benefits, so she needs children in her later years.
3. Educational environment in China. The college entrance examination system in China is the most cost-effective and successful method. If you work hard for three years, you will be admitted to a good university and have no worries for life. Because parents are a little dissatisfied with the college entrance examination, some even didn't take the college entrance examination, so the current work situation is not very good. But their children haven't taken the college entrance examination yet, so their children are expected to be admitted to a good university. Once they are admitted to a good university, their life will definitely rise in latitude, and their parents will share the benefits.
