As cultural diversity continues to advance, the existence of multicultural field is an objective reality.In the field of multi-culture, the traditional culture field, the mainstream culture field, the modern culture field and the foreign culture field are mutually interrelated, promoting and developing together.Therefore, to clarify the relationships among traditional culture, Marxism, modern culture and foreign culture is the premise and foundation of realizing the "creative transformation" and "innovative development" of the traditional culture and confirming confidence in the excellent traditional culture.However, regarding the relationships between traditional culture and the other three kinds of culture in a mechanical, static and one-sided way from the perspectives of cultural revivalism, cultural nihilism, and cultural centralism hinders the inheritance and promotion of excellent traditional culture, destroys the pattern of co-existence and co-prosperity in multi-cultural fields and influences the formation and establishment of confidence in the excellent traditional culture.Therefore, only by clarifying the three relationships concerning the development and innovation of traditional culture, correcting the ideological bias among them and resolving the divergences in the multicultural field, could the excellent traditional culture demonstrate value of the times and become the ideological source of confidence in socialistic culture with Chinese characteristics.
