The plot material of "The Head Teacher" mainly comes from the deeds of teacher Gui Xiandi, and at the same time, it incorporates the vivid cases he obtained by interviewing 100 primary school teachers in Wuhan. In order to give consideration to the artistry and commerciality of the film, The Head Teacher will be more in line with the viewing tastes of modern audiences, and boldly involve topics such as puppy love and sex education.

Director Cui Daihong said that Gui Xiandi's "Emotional Education Law" and "Education Law of Giving Love to Students" which were original in teaching and widely praised by the education sector gave him a lot of inspiration. In particular, Miss Gui asks herself "three questions" every week: "Do you love your students? Will you love your students? Do your students feel your love? " He was very moved.
