The film "Migration" is a true reproduction reflecting this history from sadness to grandeur. The film is based on the novel of the same name by Sichuan Qiang novelist Gu Yunlong. The film's creators, after two years of interviewing and researching, collected a lot of vivid and touching first-hand materials, and based on this artistic processing, the magical alpine visual elements combined with the original ecological Qiang culture, making the film has a unique epic quality.
