The public welfare of children's film is the main content of cultural exchange, supporting children's film, excavating talents of children's film, and establishing the correct values and outlook on life of children in the film industry. The greater significance lies in bringing movies to the lives of many left-behind children in poor and remote areas, investing in the shooting of child-themed movies, showing movies for free for children in poor areas, and using movies to accompany their childhood, open their dreams and warm their lives.
