Yang Xianjiang believes that education is a superstructure, which depends on the economic base. Education is not only restricted by the mode of production, but also by the political system. It also promotes economic development and political change. Education arises from the needs of social productive labor and develops in the process of productive labor; The "essence" of education is closely combined with productive labor and shared by the whole society; However, in class society, education has become a tool of exploiting class rule, and the education implemented is divorced from productive labor. He criticized such viewpoints as sacredness, lofty education, integrity and independence of education, and refuted omnipotence of education, saving the country through education and education before revolution. He thought that the only way to change the unreasonable social system at that time was to carry out revolution. In the revolution, education should be one of the weapons of revolution; After the victory of the revolution, education should promote the construction of socialist society. Yang Xianjiang is also very concerned about teenagers' political thoughts, morality, study and healthy growth. He advocates "lifelong guidance" for young people, and the key is to let young people establish a revolutionary outlook on life.
