Paper cutting is a unique form of Chinese folk art and has a history of more than 2,000 years. Paper cutting probably originates in the Han Dynasty, following the invention of paper. Since then, it has gained popularity in many places of China. The materials and tools used for paper cutting are simple: paper and scissors. Paper-cuts are usually made of red paper, because red is associated with happiness in traditional Chinese culture. Therefore, on festive occasions such as weddings and the Chinese New Year, red paper-cuts are the first choice for decorating doors and windows.
