Abstract:The “Li” is the premise and linkage of the traditional social relationships and social structures with such features such as normativity,otherness,fairness and orderness.“Li” has become something that has been internalized in the mind and externalized in the behavior,from which anyone in the world can also not depart for a while.With the help of it,everyone is indoctrinized into a social man and form a family and clan,community organizations and even the nation state.Meanwhile,it takes the shape of the complete social value system and the differential mode of association of social norms and institutional system,which also promotes the social governance and social changes.By drawing lessons from the thought of the “Li”,it is necessary to set up the social development concept of differences in fairness and truly standardize the social behavior of people in order to achieve the harmony between body and mind,oneself and others,nature and man.It is also supposed to take multiple integration of social development strategy and adopt progressive social construction path,promote the organic unity between the value scale and blueprint design about the social development,and between normative system and integration means.All of these can advance the practice of construction on harmonious society in contemporary China,and provide strong support for the formation of Chinese sociology discourse system
