The occurrence, development and ending of the contradiction between the protagonist, Mr. Wei, and the student, Zhang, is almost the whole content of the film, and the theme of the film is gradually manifested with the change of this contradiction.

As a teacher, Wei has her own shortcomings, but as a person, she has a bright spot, and these shortcomings cannot be concealed. It is easy for us to think that we can be a qualified teacher, not a qualified person in the pure sense, and vice versa. What impressed me the most was her spirit of doing her duty, not giving up until she reached her goal, and going all the way to the dark. Isn't this more educational for men, women and children from all walks of life in the whole society? Isn't it instructive for those who are half-hearted, cold-shouldered and unable to persevere in their lives and work?

In the film, the language and practical actions of "there are twenty-eight people in the class, no one can be left behind" well reflect the hero's strong and unyielding character. Because the spirit of exerting life energy to the extreme to realize one's beliefs is always admirable and moving, imagine how many people in real life treat practical difficulties with such an honest and tenacious attitude? Especially since the reform and opening up, the rapid improvement of people's living standards and the rapid expansion of material civilization have become the most beautiful excuses for many spiritual emptiness. They take this as the reason for the ideological corruption and decadent life of the dance academy, but there is a touching philosophical saying: if you drink today, you will be drunk tomorrow, and if you eat, drink, gamble and gamble, you will not waste your life. You see, how smart and open-minded. More heartbreaking than Jin Jian, no one can turn back, and no one is righteous. It is much more generous than the martyrs who were caught dead before fighting for the ideals of mankind during the revolutionary period. Everyone knows that it is always sad to enjoy a mind that cannot be created, especially those who put personal interests above all interests.

In the film, Wei's figure is elongated by the sunset, and the TV station gate says, "Are you a director?" How exciting the voice of inquiry is, it is a rational call to all listeners-no matter what difficulties lie ahead, just look for them. The reason is simple: no one can be left behind. I think there is only one word to sum this up: stubbornness! It's amazing, convincing, shocking and unforgettable.
