"Liuqing" is a unique bamboo carving technique combined with calligraphy, painting and carving, and is a re-creation of calligraphy and painting on bamboo skin. According to data and physical research, Chinese people began to use bamboo for carving in the Tang Dynasty, but because bamboo is not easy to preserve, it is difficult to pass it down. Since the Ming Dynasty, literati artists have developed on the basis of their predecessors, improving bamboo carving from a relatively simple, practical handicraft to a relatively detailed, appreciation-oriented artwork, and gradually formed a specialized art with a certain scale. In the Qing Dynasty, the form of carving has undergone more changes, and many carving techniques such as deep carving, openwork carving, round carving, intaglio carving, and Liuqing have emerged. Liu's Liuqing bamboo carving in Putian uses techniques such as tracing, carving, digging, and scraping, using the different color differences between bamboo skin and bamboo muscle, combining the brush and ink elements of Chinese painting, focusing on the unity of knife techniques and painting brushwork theory, and cleverly writing articles on a thin layer of bamboo skin to express brush and ink, meaning and knife flavor. Most of Liu's bamboo carvings are carved on pen holders, armrests, paperweights, folding fans, etc., becoming elegant playthings on the desks of scholars; and they can be combined with wood crafts, with dark hardwood as the base background, carved screens, inserts, hanging scrolls and other works, and small pieces are inlaid with light-colored materials such as ivory jade and boxwood, which are harmonious and artistic, and have better artistic effects. After being passed down for seven generations by Liu, after nearly a hundred years of development, their works are exquisite and ingenious, with both the roughness of northern prints and the beauty of southern silk embroidery and painting. In modern times, bamboo carving has been passed down in an orderly manner in a difficult historical environment, and can innovate while inheriting traditions and combining modern aesthetic tastes. The longer the bamboo carvings are collected, the more coordinated and vivid the colors between the bamboo skin, bamboo stalks and bamboo bottom are, and the longer the bamboo bottom undergoes the natural oxygen process, the redder it becomes, and the better the visual effect of the surface, which has a high artistic and collection value, greatly enriching the connotation of folk arts and crafts.
