Abstract: Based on the understanding of the connotation of library, it is the dissemination of knowledge for people, the symbol of culture for regions, and the expression of civilization for times. Therefore, the construction of library needs to answer the question of coordination between regional culture and modern civilization. Taking the library of Guizhou Anshun Vocational and Technical College as an example, the project explored a way and strategy of 'dialogue between tradition and modernity’ based on an attitude of regression and introspection. The design applied the theory of local and thinking of place. Through the interpretation of the project site, the integration of terrain, the cause of climate and the reconstruction of space, the building returned to a local expression and reshaped a place spirit. The design exploration of the project is not a symbolic reappearance of tradition and place, but an interpretation of a regressive design strategy in a critical and introspective way in the context of the times. It is regarded as a reference of traditional regional architecture practice as well as a comparison of design methods.
