In Chinese films with intangible cultural heritage themes, female images are an indispensable presence. Particularly, several renowned female hero figures derived from folklore literature, such as Liu Sanjie, Ashima, and Hua Mulan, stand out as symbols of both traditional Chinese heroines and the cultural zeitgeist. This paper utilizes Roland Barthes' semiotic theory to analyze the characteristics of these three representative intangible cultural heritage-themed folk literature films. By employing text analysis methods, it examines the elements of costume, dialogue, setting, and plot in these films. These symbolic elements elucidate the development of female characters and cultural transformations, revealing how traditional culture is represented and transmitted in modern media. The paper also explores the crucial role and value of women in the preservation and inheritance of intangible cultural heritage, offering suggestions for better shaping the images of female heroes in intangible cultural heritage-themed films.
