The development of civilization entails the emergence of new media, that also become new channels for the dissemination of works of art and the source of apparition of new forms of art. From textual narration to the theater stage and video screen, the cross-media dissemination of the story of the White Snake can be summarized as the cross-media transmission of cultural heritage, which is also a completely new aesthetic experience that can be viewed both from the point of view of external form and from the point of view of internal content. In terms of form, the evolution of media technology has led to a change in artistic thinking, especially with regard to the formation of a character that vividly represents the cultural core of the White Snake legend on the screen. From the point of view of content, the spiritual subtext of the plot is the enduring idea of caring and humanism, which allows the cultural core of the legend of the White Snake to change its media form without changing its essence.
