After thinking about it carefully for a while, I felt that it was necessary to overcome the fear that physics gave me back then.
The physics teachers I taught since childhood were not very good. As a physics teacher, I will definitely teach better than them. Anyway, I hope to teach it in my own way. The ones I recognize more are the physics teachers in the first and second years of high school, the mathematics teachers in the second half of the second year of high school, and the chemistry teachers in the second year of high school. This is very bland, but has a nice professional feel. The other teachers added their own emotions to their words, and their tone of voice made people sleepy.
By the way, I had insomnia yesterday because I fell asleep after listening to physics for a while.
Intention: Memorize the knowledge points in reverse order
