Abstract: This paper questions the point of Liang Chen and Li Zhongqing，who state that China has accomplished a “silent revolution” in the field of higher education in 50 years after the founding of the PRC.The proportion of workers and peasants’children who attend university shows two different trends before and after the reform，so it should not be simplified to “a revolution in 50 years”.Before the reform，the equality of higher education was surrounded by thick atmosphere of class struggle，so it is “equality within the class”.The practice of using political means to restrict and deprive the education right of some citizens and force some other citizens attend the university，should not be defined as progressive educational revolution.After the reform，though the promoted key middle school system allows a few rural students to enter universities，it is not a good solution to urbanrural educational inequality，but will further solidify the inequality.Among the ways which provide rural students with accesses to universities，the key middle schools and county schools with centralized resources have instrumental rationality to some extent.However，this instrumental rationality lacks moral support of value rationality，and therefore leads to unsustainability and high cost of the system.This paper also questions the concept and data used by Liang Chen and Li Zhongqing.Vague concepts such as “cadres” and “children of workers and peasants” are used in their study，thus cause problems in the quality of their data.

Key words: revolutionized education , urbanrural educational inequality, key middle school ,  education revolution
