Abstract: On December 5, 2018, the Helsinki Central Library, which attracted the attention of the global cultural community, was grandly opened. Wu Jianzhong believes that the library is a “public space open to all” and has the functions that a new generation of libraries should have, namely, serving urban innovation, improving urban features and helping with people’s comprehensive development as a communication center,learning center and knowledge center, as well as setting an example for the transformation of the global library space. Cheng Huanwen transliterated the name of the library "Oodi" into the Chinese characters , meaning “invincible”, expounding the invincibility of the library from the aspects of its architectural
design and space function design. He believes that the expansion of public library space resources and the diversification of spatial functions will surely become the development direction of public libraries and will reshape the future of public libraries; Cohen Diana and Lesneski Trach endorced the building’s architectural and construction concept from the perspective of architectural design. The library architectural design aims to provide support to people of all walks of life as widely as possible, so that all users can have equal access to the library space, feel dignified, and use the library in a comfortable and relaxing environment. They consider the library has set a good example for city residents of the world participating in the construction of cultural places. At the same time, they emphasizes the importance of the inclusive design of library buildings, and highly appreciates the inclusiveness displayed by this new library building. Tang Yuen takes the geographical location, floor distribution, architectural design and actual situation of the library as examples to propose that for different countries and regions, the design of the public library should reflect the characteristics of the library and adapt to the local social and cultural needs so as to showcase its cultural characteristics. Ehriver Turnstay and Chris Hardy believe that the library must be open enough, and its structure allows users to create, define, and influence the overall environment. At the same time, library design must have architectural originalities, which can provide users with pleasure and enhance the pride of citizens. They believe that the library will become a new cultural hub and witness the library functions as an open structure.
