"Good Teacher" is a youth campus movie, which is supervised by Qian and directed by Zhang Luan, and starring Yu Qian, Qin, Sun Yiyang, Lu Daxu, Hao Pengfei and Gao Gao. With Miao Wanqiu as the core figure, the film focuses on the interesting story of Miao teacher and students' "wits and courage".

Film evaluation

"Good Teacher" not only artistically reproduces the "truth" of that era-the innocence of campus, the frankness of students and the sincerity of teachers, but also passionately expresses the "feelings" of that era-the true feelings of loving students, hazy love and mutual friendship. This kind of "truth" and "emotion", as well as their proper presentation, endows the film with a special style and charm, makes lame stories interesting, and makes rough characters flesh and blood.

With this "truth" and "emotion" as the background, the smiles inside and outside the film point out oily jokes, and the tears are different from the feelings after sensationalism. This kind of "truth" and "affection" is not only lacking in educational films, but also a long-lost phenomenon in increasingly specialized campus life and teacher-student relationship.
