Abstract: The production technique of Xuan writing-brush, which is one of China's national intangible cultural heritages, has been inherited for more than 2,000 years. After going through ups and downs, it has been handed down to the present day. However, in the process of inheriting and developing this production technique, some problems have arisen, such as an obvious aging trend of inheritors and limited operation mode with shops in front and workshops in back. Therefore, it is necessary to speed up the legalization process of intangible cultural heritage protection, improve grass-roots institutions for intangible cultural heritage protection, strengthen the norms of productive protection and strengthen the protection of inheritors and so on.
