China is paying more and more attention to public libraries, and people are encouraged to make full use of them. The newly published statistics show that the number of public libraries in China is increasing year by year. Many libraries have created a quieter and more comfortable environment for readers through refurbishment and expansion. Large public libraries not only provide a wide variety of reference materials, but also regularly hold activities such as lectures, exhibitions and so on. In recent years, there have also been many digital libraries which can save the space to store books. Some libraries have also introduced self-service systems, making it more convenient for readers to borrow and return books, which further meets the needs of readers.
