Abstract: The long-standing problem of teachers' paid compensated tuition is, in a sense, not simply an educational issue, nor simply an issue of teacher's ethics, but a reflection of the social development of Chinese society in the social subsystem of education. The external causes of the problem mainly include:the overall anxiety of people in the process of modernization and social transformation, the influence of the "theatre effect" on the real values of educational development, and the failure of some educational administrative departments to monitor the situation. The internal roots of teachers' paid compensated tuition mainly include the fact that the phenomenon of teachers' paid compensated tuition is itself a huge market of " hit it off", and that some teachers have a low level of teacher ethics. There are three ways to solve the problem of teachers' paid compensated tuition:first, creating a value identity of " shouldn't have" by strengthening teachers' ethics, so that teachers " do not want" paid compensated tuition; second, creating a "redundant" exit effect by raising teachers' income, so that they are "unwilling" to do paid compensated tuition; third, creating an institutionalized " daunting" preventive mechanism, so that teachers " cannot" do paid compensated tuition.
