A Study on the Symbolic Dissemination of Traditional Intangible Cultural Heritage Videos from the Perspective of Symbolic Interactionism—Take the Video "China in Non-Heritage" as an Example

Aiming at the survival challenges and development problems of traditional culture on the new media platform, and proposing the development path of non-heritage culture based on the perspective of symbolic interaction theory, this paper uses the content analysis method to analyse the establishment of the symbolic system as well as the cultural interaction strategy and effectiveness of the programme "China in Non-Heritage", and puts forward the strategic significance of this programme for the development of non-heritage culture. The study breaks through the limitations of traditional communication modes and proposes the integration of symbolic interaction strategies for the dissemination of non-heritage culture in the context of new media, providing theoretical support and practical paths for the construction of a cultural communication system in the digital era.
