You can't. In July 2020, the Ministry of Education issued the Measures for the Administration of Extracurricular Reading Materials for Primary and Secondary School Students, stipulating that no unit or individual may sell extracurricular reading materials on campus by holding lectures, training and other activities. For the extracurricular reading materials donated for public welfare, the school should make clear its source, and the school or the higher education administrative department should review and check them. So it is impossible to sell social science books in our school through students at school.
