I have been alienated from my father because of a childhood trauma, which I have been struggling with as I grow up. When I was filming Guo Li, who became an activist for his daughter, I gradually became curious about the similar alienation between them. In this process, I kept exploring and gradually returned to my own family, and finally picked up courage to face that childhood trauma and raised my questions. Although the ending is yet to be reached, making the film helps me to heal, to relieve, and to become more mature than before.
