China attaches increasing importance to public libraries and encourages people to make full use of them. The newly released statistics indicate that the number of public libraries in China is on an increase year by year. Many libraries have created a quieter and more comfortable environment for readers through renovation and expansion. Not only do large-scale public libraries provide a wide range of reference materials，but they also regularly hold lectures, exhibitions and other activities. In recent years, there have also been many digital libraries, saving the space needed to store books. In addition, some libraries have introduced self-service systems, which make it more convenient for readers to borrow and return books, and further meet the needs of readers.
