Papermaking is one of the four great inventions of ancient China. Xuan paper is an outstanding representative of traditional handmade paper, with the characteristics of being tough and resistant to moths and rots. Since the Tang Dynasty (early 8th century AD), it has been the best carrier for calligraphy, painting and classic printing, and it has not been replaced by machine-made paper to this day. The traditional Xuan paper making technique has 108 steps, with strict requirements on water quality, raw material preparation, utensil making, and process control. This technique has been passed down from generation to generation through oral transmission and continuous improvement, combined with a variety of cultural elements, which has had a profound impact on the inheritance of Chinese national culture and played an important role in promoting national identity and maintaining cultural diversity.
