In the past, I have always said that there should be no applause during speeches, and people should be allowed to doze off and rest their minds. When I was studying in the past, I read novels, and when the teacher checked, I would put the textbook on top of the novel. This may be my fault, or perhaps the teacher was wrong, and it was better to read novels. Later, I invented the idea of being allowed to doze off. Don't say that I am a person without creativity; I still have some. In this way, it will rectify those who give lectures in a dictatorial style rather than a conversational style. If there are lecture notes, there is no need to lecture again.
