“Cải lương miệt vườn Nam Bộ” (Southern Vietnamese cải lương - reformed opera) faces growing risks of decline amid digital transformation. This article analyzes the case of the “Ngôi sao miệt vườn” (reformed opera talents) program, an online media product combining social media influencers and professional cải lương artists in Southern Vietnam, drawing on theoretical frameworks of community communication, living heritage theory, and an interdisciplinary approach across cultural studies and media studies. The findings clarify the transformation of performance spaces to digital platforms, the role of seasonal content formats in building online audience communities, social inclusion values, and the proposal of a community digital heritage communication model as a new cultural institution, with practical policy implications for intangible cultural heritage preservation in Vietnam.
