The rapid development of Internet，cloud computing and large data technology has affected and changed people's traditional way of life and production methods.In order to make the public cultural service more convenient and more broadly meet the growing cultural needs of the masses，it is an indispensable way to utilize the integration of science and technology and rely on “Internet + culture” to promote the development of public culture.In recent years，in the exploration and construction of modern public cultural service system，directed by basic cultural needs of the masses，taking the public cultural products as the content，Chongqing City has built a unified “city-county-town tertiary interconnected” public cultural Internet of Things service platform，and relying on the form of cultural volunteer service，the city mobilized all forces and established a new public cultural service model of “common people order，government distribution”.
