The traditional Chinese morals,with more than two thousand years of evolvement,have contained various virtues and standards.What are the relationships among all these numerous ethical ideas? This paper,based on the philosophical framework of ontology-practice,puts forward an inherent structural model of two-dimensions-four-sides-three-levels,which contributes to a new orientation of the traditional Chinese moral ideas.Specifically,the "two dimensions" mean man’s individual and social existence,the "four sides" embody the base Noumenon,realm Noumenon,knowing work and practice work,while the "three levels" mean the ontological level formed by the basic categories of Way,Character,Great and Holy;the practical level constituted by the fundamental ideas of Benevolence and Ceremony;and the ontological-practical level made up by the radical principles of Earnestness,Brightness,Wisdom and True.
