In the era of digital media, the cross-cultural dissemination of intangible cultural heritage in China encounters two major problems due to language barriers and the difficulty of rewriting stories with traditional themes into new narrative forms. This paper takes Fuzhou tea culture, a national intangible cultural heritage project, as the research object to explore the effects of applying AI-aided translation of short videos and social network communication modes to this intangible cultural heritage project. The study finds that using artificial intelligence for multilingual translation can overcome language barriers to a certain extent, enabling people to understand relevant cultural content relatively easily, while short videos can enhance people’s sense of affinity for the culture through a combination of pictures and texts. The communication mode that combines the two can be regarded as an attempt at integrated media. Both can provide foreign audiences with a low-cost and highly efficient way to understand and spread Chinese Fu Tea culture. Based on the experience of making short videos and conducting Weibo promotions by myself and others in the past, this paper proposes a workflow of “AI Preliminary Translation + Human Polishing + Weibo Promotion”, and puts forward opinions on aspects such as content format, technical ethics, and communication effects.
