From the beginning to the end, he got along well with his classmates. This is a gradual process, the process of his growth as a class teacher and the process of his students' growth. This movie is funny, relaxed and humorous, and it looks ridiculous. But on the other hand, the film is also very touching. He witnessed all kinds of interesting things between the class teacher and the students.
The head teacher in the film educates and teaches students in his own way, so that students can develop in a good direction gradually. What impressed me most was that his students were arrested by the police when they entered the police station. He went to his brother-in-law and begged the students to let him go. Another place that impressed me very much is that Zhao Rongbao, the head teacher, has a bike that he likes very much. He won the prize, so he likes it very much. This is his honor as an excellent teacher, but it was ruined by naughty students. Although he was angry, there was nothing he could do. But later, his practice touched the students, so the students bought him a bike. These things have witnessed the friendly feelings between teachers and students.
Another thing is that his students became seriously ill, and then everyone collectively donated money for him. This is also a plot that moved me very much.
