I want to be a director in the film industry, but now I have no experience or professional knowledge. Where can I find a formal job as an intern director?

You can go to the advanced class of Beijing Film Academy. The director has no apprenticeship. . . Unless you join a group, you should also start with small work such as recording the scene. You can't be an assistant director or an assistant director when you come up. . If you want to enter the profession, I suggest you take a refresher course. Or, let friends related to this industry introduce the work of the group.
