Teaching means not teaching. According to China Education News Network, Ye Shengtao was an outstanding educator in China in the 20th century. His educational thought of "teaching is for not teaching", based on the practice of social reform and education reform in China in the 20th century, has built a modern educational and teaching theoretical system with local original significance and rich scientific connotation, showing a profound cultural background and lofty ideological realm. The educational thought of "teaching without teaching", with the broad vision of "trying to integrate with the world's academics" and the consciousness of the times of "keeping pace with the times", criticizes "the old-fashioned education of classicism and legalism", criticizes the disadvantages of "treating students as empty bottles" and criticizes the stubborn disease of "exam-oriented education" that seriously hinders students' independent and all-round development.
