As far as I know, Mr. Qiao Liang studied Chinese as an undergraduate, and later studied for a master's degree in the director department of the Film Academy and a doctor's degree in the film department. Therefore, Mr. Qiao Liang studies more about the combination of literature, script and director's second creation. Teacher Zhang Jiandong of Wang Ruihe graduated from undergraduate course and stayed in school to teach directly. Teacher Wang Rui graduated from the Department of Directing, and Teacher Zhang Jiandong graduated from the Department of Acting, so she may be more inclined to study performance and direction.
In short, as a graduate student of the director department, any teacher can only be inclined within the framework, and there is no need to care too much about the teacher's preferences.
I wonder if the answer is satisfactory?
