The construction of a discourse system in colleges and universities to consolidate students'' sense of the Chinese nation''s community has both theoretical possibility and practical feasibility. The construction of a discourse system in colleges and universities to forge their sense of the Chinese nation''s community is an important way to inherit and develop Marxist theory and consolidate the ideological front. In addition， it is a major approach to the integration of national cultures and modern cultures for students'' deeper sense of national identity. The discourse system with which colleges and universities create their awareness of the Chinese nation community among college students needs to be enhanced in its credibility from the academic dimension， to be improved in its affinity from the value dimension， and to be intensified in its popularity from the practical dimension. Consequently， the sense of community of the Chinese nation can be highlighted and refined among college students.
