Yangzhou was one of the places in China where paper-cutting first became popular. The custom of cutting paper to herald spring came into being in the Tang (618-907) and Song(960-1279) dynasties. Yangzhou people cut papers into flowers, butterflies or other tokens of spring on the first day of the season. The papercuts are hung on the heads of beautiful women or placed on flowers for people to see. Paper money and horses are cut for memorial ceremonies. The art reached its peak in the Qing Dynasty (1644-1911). Since then, many artists have worked on paper cutting techniques, including Bao Jun, who was known for his extraordinary skill. The paper cuts can be used to make door curtains, bedding and clothing, and purses and pen bags.
