The national narrative of China's films is reflected in many aspects. First of all, China films often take the history, culture and society of China as the background, and convey national feelings and values by telling stories of China people. Secondly, China's films focus on the lens expression to show the aesthetic elements of China's characteristics, such as landscape painting-like natural landscape, traditional architecture, costumes and so on. At the same time, China films also emphasize the uniqueness of China culture by dealing with language, music and rhythm. This kind of national narrative and lens expression not only makes China's films have a unique style, but also helps the audience to better understand and feel the charm of China culture.
