Near the market of the White Pagoda in Beijing, youngsters learn a lesson from the poster: “When your classes are finished, you run to your home. But Mama will not be there, for she has gone to school.” The poster also urges the founding of secondary schools for those who cannot read, in order “to sweep away Illiteracy.” The walls of city and country buildings are covered with educational and political posters, each with its lessons, each with its slogan.
