In the context of anti-globalization, short-video platforms represented by Douyin have restructured the paradigm of cross-cultural communication and formed a new order of “platform-based survival.” This study takes foreign bloggers on Douyin as the research object and uses interpretive qualitative research methods to analyze their video texts, interactive contexts, and cultural practices through cultural depth description, multi-source triangulation verification, and critical deconstruction. The study found that foreign bloggers, through a three-dimensional integration strategy of “cultural symbols — emotional narratives — social practices”, used cultural contrast to create attention anchors, family narratives to reconstruct identity, and professional experiences to deepen social connections to construct dynamic cross-cultural dialogue mechanisms. Their communication practices not only break the one-way “gaze of the other” but also break down cultural barriers through symbolic interaction, emotional resonance, and participatory communication, forming a “micro-infrastructure” for mutual learning among civilizations in the digital age. The study provides a theoretical and practical basis for breaking through the theory of “civilizational conflict”, protecting cultural diversity, and building a community with a shared future for mankind.
