For a long time in the past, in the eyes of many people, intangible cultural heritage was like an old antique, a bit cold and suitable for display on museum shelves, "it can be viewed from afar but not played with profanity. In recent years, as long as you pay a little attention and observe, intangible cultural heritage has entered our lives. From bookmarks, stationery, tea cups to fashion, home appliances, digital products, from eating and drinking to playing and using, many things in our lives contain intangible cultural heritage elements. It is design that brings intangible cultural heritage into modern life. Design has made intangible cultural heritage "live" and "trendy". At the same time, intangible cultural heritage has also brought a lot of inspiration, materials, and means to design. Intangible cultural heritage enriches the language of modern design. Design language is a symbolic system in which a work can express itself and communicate with viewers and users. The appropriate choice of design language will directly affect the acceptance of the work. China has over 100000 representative intangible cultural heritage projects at all levels, covering ten major categories, including folk literature, traditional music, traditional dance and drama, traditional art, traditional techniques, and folk customs. By extracting, segmenting, and deforming information from different intangible cultural heritage projects, designers can analyze different visual symbols, providing rich design language for specific product designs. The buildings in the Forbidden City were constructed using the technique of firing glass. The Palace Museum Cultural and Creative Center extracts elements of glass components and designs a silk scarf with both glass and fashion elements, with the theme of "colorful scarves picked from the palace wall". As is well known, in the past, it was not allowed to plant flowers, plants, and trees arbitrarily within the Forbidden City, so the glass on the palace walls was originally regarded as a "wall flower" and was a decoration and embellishment of palace architecture. Integrating the element of "Palace Museum glazed flowers" into the design of silk scarves not only attracts people's attention to the ancient glazed firing techniques, but also enriches the cultural connotations of silk scarves products. Some intangible cultural heritage techniques are directly applied to product design, which is quite common in clothing design. Embroidery and tie dyeing are both traditional handicrafts in China, and many embroidery and tie dyeing techniques have been included in the list of intangible cultural heritage at all levels. Nowadays, in the field of fashion design both domestically and internationally, how to apply embroidery and tie dyeing techniques has become a "prominent subject". Designers combine traditional techniques such as dyeing, weaving, and embroidery with modern aesthetics to design various clothing that combines practical value and aesthetic functions, which has gained widespread recognition from consumers. Nowadays, more and more young designers are actively entering ethnic regions, learning from non genetic inheritance and learning intangible cultural heritage skills in order to gain more design inspiration and enrich their design language. The use of intangible cultural heritage elements in modern design is both a process of deconstruction and a process of reconstruction. In the deconstruction of intangible cultural heritage, the capture and use of intangible cultural heritage elements can enrich design language, improve design efficiency, and make products more aesthetically pleasing. Through the reconstruction of intangible cultural heritage, designers no longer only obtain specific design symbols, but a complete set of cultural concepts. Designing based on this concept is not only for the purpose of designing good products, but also for cultural dissemination, with the aim of bringing the public closer to the design object from the dimensions of relationships, emotions, and culture.
