Chinese paper cutting is a unique art form and has existed for thousands of years with a long history featuring both national and regional themes. Paper began as a precious commodity in the Han Dynasty. Most of the people with access to paper for an entertainment cause such as art were usually nobles in royal palaces. The Song Dynasty scholar Chou Mi mentioned several paper cutters who cut paper with scissors into a great variety of designs and characters in different styles, and a young man who could even cut characters and flowers inside his sleeve. The oldest surviving paper cut out is a symmetrical circle from the 6th century found in Xinjiang, China.
