Filial piety culture is a vital basis for the adjustment of intergenerational kinship in ancient society. It mainly experienced three stages of development: infancy, Confucianism and legislation. The current social structure of our country and the social environment on which the traditional filial piety culture relies have undergone major changes, leading to the historical limitations of the filial piety culture becoming more prominent. In the era of comprehensively governing the country according to law, the contemporary jurisprudential value of the traditional filial piety culture should be explored and legislation should be introduced to promote the stability of family units with invisible contractual relations, the development of social ethics with family ethics, and the promotion of rule of virtue with the promotion of filial piety culture. The rule of law is organically combined, combining spiritual support with material support to build an elderly law system with Chinese characteristics that has traditional cultural characteristics; At the same time, we should improve the protection of culture, legislation, judicature and institution, establish the accurate concept of filial piety culture, realize the organic connection between hard law and soft law, play the role of mediation in dealing with intergenerational kinship issues, realize the transition from individual pension to social pension, and deal with the intergenerational contradictions in social transformation.
