After class last night, I attended Zhao Ruoyu's graduation poem recitation in Wenshan Lake. A * * *, including me, has only four listeners. However, my heart is full of warmth, as if I had returned to Tsinghua many years ago and lived poetically with Jiang Tao and Youtie.

I met three colleagues in the staff canteen this morning. I told you what happened to me last night. Several colleagues were deeply impressed by Ruoyu, saying that he was a student with great personality, and he would express dissatisfaction with the teacher's teaching methods. I laughed after listening to it, because when I was in Peking University, I also refused to attend a teacher's class, but the reason was that I couldn't agree with the teacher's political stance. In my opinion, a person who can't even tell the devil from the savior is qualified to occupy the forum of Peking University. Now that I am a teacher, I will generally be more tolerant of students with personality. In my opinion, college students can be absent from class, be late, leave early and argue with teachers, but there is only one thing that they must not do, that is, not to read books or classic books. Read more classics and come to class. Some students are consuming the content of the teacher's lecture, thinking for thousands of years in class and daydreaming. You might as well read more books yourself.
