Paper-cutting is introduced as follows:

Chinese paper-cutting is a folk art of cutting and carving patterns on paper with scissors or carving knives, which is used to decorate life or cooperate with other folk activities. In China, paper-cutting has a broad mass base and is integrated into the social life of people of all ethnic groups. It is an important part of various folk activities. Its continuous visual image and modeling form contain rich cultural and historical information.

It expresses the social cognition, moral concept, practical experience, life ideal and aesthetic taste of the general public, and has multiple social values such as cognition, education, expression, lyricism, entertainment and communication.

The history of paper-cutting is as follows:

Paper was invented in the Western Han Dynasty BC, before which there could be no paper-cutting art.. But at that time, people used very thin materials to make handicrafts by hollowing out and carving, but it was popular long before paper appeared, that is, patterns were cut on gold foil, leather, silk and even leaves by carving, carving, picking, carving and cutting.

In Historical Records Jiantong Named His Brother, it is described that in the early years of the Western Zhou Dynasty, the leaves of the pole were cut into "poles" and given to his brother, and they were named Tang Hou. During the Warring States period, leather carvings (one of the cultural relics unearthed from Chu Tomb No.1 in Jiangling, Hubei Province) and silver foil carvings (one of the cultural relics unearthed from the Warring States site in Guwei Village, Huixian County, Henan Province) were all exactly the same as paper-cutting.

Paper-cutting in Tang Dynasty is introduced as follows:

Paper-cutting has been in a period of great development in the Tang Dynasty. In Du Fu's poem Peng ADB, there is a saying that "warm soup is enough for me and paper is enough for my soul", and the custom of evoking souls by paper-cutting has been circulated among the people at that time. The paper-cut in the Tang Dynasty, which is now in the British Museum, shows that the paper-cut at that time had a high level of manual art and a complete picture composition, expressing an ideal realm between heaven and earth.

Popular in the Tang Dynasty, the carved patterns of flowers and trees have the characteristics of paper-cutting. For example, the pattern of "Duiyang" in Masakura Hospital in Japan is a typical artistic expression of hand cutting. In the Tang dynasty, there was also block printing made of paper-cutting. People carved it into wax paper with thick paper, and then printed the dye on the cloth to form beautiful patterns.
