First, the period of single function view. Newman's single-function view means that the only function of an ideal university is teaching, pursuing profound knowledge and cultivating outstanding members for society.

Second, the period of dual-function view. The dual-function view represented by Humboldt spirit is a new university that advocates the unity of teaching and scientific research, insists on talent cultivation and scientific development, and should maintain the principle of "loneliness and freedom".

Third, the multi-functional period. "Wisconsin Thought" and its practice have promoted the social service function of colleges and universities and extended the third function of colleges and universities-serving the society.

A university refers to an ordinary institution of higher learning. This is an organization with unique functions. It is an institution of higher learning that inherits, studies, integrates and innovates advanced academic knowledge, and is interrelated with social, economic and political institutions.

It is not only the product of the development of human culture to a certain stage, but also a unique culture gradually formed on the basis of long-term school-running practice through historical accumulation, self-efforts and external environmental influence.

The five basic functions of a university are: talent cultivation, scientific research, social service, cultural inheritance and innovation, and international exchange and cooperation. Higher education is an important supplier of talent training, and the primary and essential function of universities is talent training.
