(1) In the discussion of teachers' tasks, Han Yu put forward the famous conclusion that "an ancient scholar must have a teacher, so he preached, taught and dispelled doubts". These three basic tasks of teachers are closely related. They focus on preaching, and teaching is for preaching. The Six Classics of Ancient Chinese is only a tool to carry the Tao, and preaching and teaching is accomplished through teaching. This reflects the basic spirit of the Confucian tradition of "protecting teachers and observing Taoism", with "preaching" as the primary task, "teaching" as the second task and "dispelling doubts" as its due position, so the order is clear.
(2) Regarding the relationship between teacher and Tao, the dialectical relationship between teacher and Tao analyzed by Han Yu is also reasonable, pointing out that "where Tao exists, there is a teacher", and teacher and Tao are closely integrated and inseparable. The "teacher" of students is the "Tao" of teachers. To preach, teach and solve doubts, there must be a teacher, and those who respect the teacher can defend the Tao. Being a teacher is "preaching". If a teacher can't "preach", he can't call a teacher.
(3) Regarding the relationship between Tao and karma, Han Yu pointed out that Tao is the Confucian orthodoxy and basic spirit, while karma is a Confucian classic and a tool to carry Tao. Between the two, "Tao" is the most important, followed by "karma"; "Tao" is the first, and "industry" is the last; Tao is embodied by karma, and karma serves Tao. If a teacher just "learns to read his sentences" without preaching, it is "left over from primary school", that is, because of "small", he loses his "big" and forgets the fundamental task.
(4) In the aspect of teacher-student relationship, Han Yu proposed that teachers should master the Tao and learn the major first, and teachers are not limited by any age, status or qualification. It is pointed out that "disciples do not have to be inferior to teachers, and teachers do not have to be superior to disciples. They learn the Tao in sequence and specialize in their skills, that's all." This reflects the objective law of moral knowledge accumulation and teaching, that is, listening to "Tao" first and "feeling before feeling"; The objective law of the teaching process of "knowing" and "not knowing" in college.
In a word, Han Yu's exposition on teachers' tasks, teaching methods, career and the relationship between teachers and students contains elements of naive dialectics. It is suggested that teachers should be loyal to their ideals, spread the truth, learn to have expertise and teach seriously. It is suggested that teachers should not only take the lead, but also attach importance to teaching and learning, and those who have the ability should be teachers. These insights enriched China's ancient educational thoughts, and also have certain reference value and enlightening significance today.
