On 22nd of January, 2022, IFLA formerly issued Tendency Report, a new edition of 2021.It is the first one since the epidemic and also a new scan of the living and developing condition after two years of epidemic, reflecting a general judgment of the library all over the world about the developing direction and social environment, and so it is important for library's plan and development. The author put forward three suggestions, through a deep interpretation of the report, that libraries in our country should strengthen social responsibility idea and expand service range in the post-epidemic time; increase the soft ability to solve the social problems; eliminate latent problems in service.
