This study explores the practice, challenges, and opportunities of multimodal dissemination of lacquer art from the perspective of digital humanities. It begins by reviewing the development of digital humanities, emphasizing its application in art and cultural studies, particularly in the field of lacquer art. Through case studies, the article examines the multimodal expression and dissemination of lacquer art in digital environments, such as the use of 3D modeling, virtual reality (VR), and augmented reality (AR) technologies. These technologies not only enhance the interactivity and experiential quality of lacquer art education but also facilitate its international dissemination. The study also highlights the technical and cultural challenges faced in promoting traditional art through digital means, including high costs, technical barriers, maintenance requirements, and the difficulty of preserving cultural authenticity while ensuring effective dissemination. Additionally, the role of social media and online platforms in modern lacquer art dissemination is discussed ^[1]. These platforms provide extensive visibility and communication channels for artworks, fostering a multicultural community of lacquer art enthusiasts and opening new avenues for global dissemination and cultural exchange.
