Why is tie-dye an intangible cultural heritage and how to protect it?

First of all, what is tie-dye? Come to see Baidu's definition /view/147410.htm tie-dye ancient name tie val, twisted val, clip val and dyeing val, is a traditional and unique Chinese folk dyeing process. A dyeing method in which fabrics are partially tied up so that they cannot be colored, one of China's traditional hand-dyeing techniques. The definition of intangible cultural heritage: According to the UNESCO Convention for the Safeguarding of the Intangible Cultural Heritage: Intangible cultural heritage (ICH) refers to the practices, performances, expressions, knowledge systems and skills that are recognized as part of the cultural heritage of groups, communities and, in some cases, individuals, as well as their associated tools, objects, artefacts and cultural spaces, crafts and cultural spaces. I believe that tie-dye meets the definition of intangible cultural heritage. There are many ways to protect it, such as supporting the inheritors with financial support, selecting the inheritors of the intangible cultural heritage, scholars conducting research on tie-dye, recording the process of tie-dye, and encouraging newcomers to learn tie-dye.
