During the Cultural Revolution, most professional and technical personnel in enterprises were sidelined because of poor background or other political reasons. Later, the proletarian revolutionaries thought that no one could do it technically, so they invited people who took the road of white school to come back and do it again, but they only used it and dared not entrust it to reuse. In addition, the university has been closed for several years, and there are no new graduates to supplement it, resulting in a serious brain drain of skilled talents. These directly affect the normal progress of "grasping revolution and promoting production". In the late period of the Cultural Revolution, according to the spirit of "72 1" of the Central Committee, various units started 72 1 universities one after another.

This kind of university is to train talents for its own unit, select from workers, enter the school by open-book examination, graduate by open-book examination, and train whatever talents are needed for production. Most of the university classrooms are located in the conference room of the unit or upstairs of the staff dormitory. Lecturers can be technicians and engineers in our factory or experienced masters. Learning content is something that needs to be solved urgently in production, and the leading idea is "applying what you have learned". Although such a university had no academic qualifications and the level of basic courses was not high, it did play an urgent role in the talent problem at that time.
