Due to various factors such as multiple interest factors, changes in the social reproductive environment, increased intergenerational physical distance , and diverse ideological trends, modern society has gradually marginalized people''s kinship relationships, and the loss of family culture has led to the social phenomenon of "kinship disconnection", which in turn affects the inheritance of traditional family culture, the recognition of family values, and the harmony in family relationships. "Kinship disconnection" represents the weakening of family culture, diluting of blood relationships, depleting of interpersonal relationships, and alienation of family value identification. In order to create a favorable social environment for family relationships and eliminate the negative impact of "kinship disconnection", society, families, and individuals should work together from multiple perspectives, such as strengthening family ethics and education, strengthening public opinion guidance, spreading collectivist culture, and reconstructing young people''s values of family relationships, in order to lead “disconnected” youth to return to the home of family relationships.
