The sources of ancient Chinese traditional patterns can be roughly divided into three parts. First, it comes from folk crafts: ceramics, embroidery, window grilles, blue calico, batik, paper-cutting, carving, weaving, etc., which are created by working people according to their own will, and are generally simple, rough, and rich in local flavor. The second comes from religious art, such as religious legends and myths and legends, murals, caissons, niches, statues and costumes, bases, buildings, sculptures and various decorations in temples and caves. The most typical Dunhuang patterns are the essence of traditional Buddhist patterns. It is a unique artistic style created by my country's skilled craftsmen absorbing foreign culture. These patterns are rigorous in composition and full of ideals. The third one comes from the furnishings, daily necessities, clothing, jewelry, and buildings occupied by feudal emperors, princes, nobles, wealthy merchants, etc. These handicraft patterns are carefully designed to satisfy the material life and empty spiritual life of the luxurious. There is no special workshop and the production is supervised by dedicated personnel, so the patterns are very fine and the colors are rich and luxurious. In addition to the traditional patterns mentioned above, a considerable number of them are decorative patterns with themes of fortune, longevity, fortune, literati calligraphy, painting, and poetry. Most of them adopt metrical forms such as the "meter" pattern and the "jiugong" pattern. The above three parts of patterns constitute the mainstream of my country's traditional patterns.
