The family support is reciprocal behavior between parental and offspring under long-term agricultural civilization. Filial is the system to implement the family support. However, offspring’s benefits in the reciprocal behavior have been sharp declined under the conditions of modern industrial civilization, which leads to the gradual decline of the influence of Filial and Family Support is gradually replaced by modern pension model composed of personal support and social pension. It is necessary for government policy incentives to improve family support as a complementary role, which includes increasing benefits of family support and costs of not-support-activities. Cultivation of Filial is the fundamental strategy for the long term but not the current way to revitalize the family support.
