"On Teachers" clearly stated at the beginning that teachers' duty and role is to "teach and dispel doubts", without mentioning students' thinking problems, and students are in a passive learning state. In the Analects of Confucius, Confucius put forward that "no anger means power", which focuses on inspiring students to actively observe, think and learn, rather than inculcating and simply answering questions. Confucius' educational thought is different from Han Yu's, which, to put it bluntly, is far from being comparable to Han Yu's, so Confucius is regarded as a saint and Han Yu is only a mortal.
