Abstract: In the all-media era, revolutionary changes in information acquisition have created an unprecedented information environment and public opinion landscape. The complexity of the ideological domain continues to intensify, posing new challenges to the dissemination of mainstream ideology. To address this, it is imperative to strengthen the development of an allmedia communication system and shape a new paradigm for mainstream public discourse. First, we must embrace and adeptly drive transformative changes, confront challenges headon, deeply reflect the value orientation of the times, actively respond to societal and public concerns, accelerate the integrated development of media platforms, and enhance the reach of mainstream ideology. Second, it is necessary to analyze the contemporary challenges and opportunities by addressing the narrative crises and emerging issues in allmedia communication of mainstream ideology. Third, scientific application of agendasetting should be employed to ensure the comprehensive integration of mainstream ideology across all dimensions and levels, embedding the Partys propositions and theories into the daily lives and work of the people. Fourth, we must drive the transformation of Chinas mainstream ideological discourse system through enhancing localized theoretical innovation in communication, reforming Chinese discourse narratives, optimizing technological algorithms, and improving communication efficacy. This will accelerate the construction of a Chinese narrative system capable of effectively telling Chinas stories, communicating Chinas voice, and projecting Chinas image both domestically and internationally.

Key words: all-media, mainstream ideology, communication system
