Family virtue is the cornerstone of social morality. The Book of Rites says, "The benevolence of a family is the benevolence of a country; "One Germany, One Country", everyone's ethical value construction begins with family education. Only when the family style is good can the social atmosphere be good. History and reality have proved countless times that a good family style is the foundation of family prosperity. Zeng Guofan is best at managing the family. He often mentioned his grandfather's family motto "Morning, Sweep, Test, Treasure, Book, Vegetable, Fish, Pig", to build a self-cultivation home, a filial home for parents, and ensure that family talents come forth in large numbers. The values of "benevolence, righteousness, courtesy, wisdom and faithfulness" in China's traditional culture are all shaped and formed in family education, which has become the basic framework of social ethics and deeply safeguarded social order. Of course, China's traditional family precepts, family rules and family education are full of the essence of moral integrity and noble personality, and there are also the dregs of unequal personality such as "father as son" and "husband as wife". These dross will have a negative impact on children's growth, harmony between husband and wife and family harmony, which is not conducive to the formation of modern civilized family style. To carry forward a good family style, we should bring forth the old and bring forth the new in China's traditional moral norms and keep pace with the times. For example, in the inheritance of family traditions, the concept of equality between men and women in which husband and wife live together on an equal footing and develop together is not only the enrichment and development of traditional family virtues in the modern civilized environment, but also the inherent requirement and concrete embodiment of practicing socialist core values. Building family virtues means vigorously advocating "respecting the old and caring for the young, equality between men and women, harmony between husband and wife, diligence and housekeeping, and neighborhood unity" in the family. The Outline for the Development of Women in China formulated by our government puts forward that the establishment of an equal, civilized, harmonious and stable family is the main indicator. It requires carrying forward the fine traditions of the Chinese nation, and establishing and developing equal, United, friendly and mutual-aid family relations and neighborhood relations. In this sense, the cultivation of social morality should conform to the needs of the times, start with the shaping of family virtues, build a source of value by inheriting the tradition and advancing with the times, feel the truth, goodness and beauty in the warmth of the family, contribute the truth, goodness and beauty in the intimate relationship, work hard in practice, and work hard to build a harmonious and beautiful society with thousands of warm "small families", which is also the source and internal logic of the cultivation of social morality.
