Does anyone know the lost craft of the quintessence of Chinese culture?

Due to the impact of electric fans and air conditioners, traditional industries such as folding fans and round fans are facing bankruptcy, and many fan-making skills are lost. This is a question worthy of people's reflection.

Suzhou's fan making technology has been applied to become an intangible cultural heritage. Although protected but not driven by economic interests, its development is still limited. At present, the largest Suzhou fan is Shengfeng Suzhou fan, which is widely regarded as the inheritor of Suzhou fan technology.
