Bamboo slip carving is a traditional art of carving figures, animals, plants, patterns and words on bamboo products. It is mainly popular in the Jiangnan region. During the Tongzhi period of the Qing Dynasty, a group of Zhejiang people immigrated to Guangde and brought bamboo slip carving to Guangde. It has a history of more than 150 years in Guangde. At present, Guangde has a large number of artists engaged in bamboo slip carving. The bamboo slip carving in southern Anhui mainly adopts the techniques of "leaving green carving" and "bottom pattern carving". "Leaving green" means leaving a layer of green bamboo on the surface of the bamboo as the carving pattern; then scrape away the bamboo green outside the pattern to expose the bamboo skin below as the ground, which is called "leaving green bamboo carving". The bamboo green is selected from deep mountain winter bamboo, which is treated with mildew and moth-proofing technology, and the surface of the finished product is smooth. Bamboo is as clean as jade, and the bamboo skin has silk patterns. The bamboo is light in color and becomes slightly shiny over time; the longer the bamboo skin is, the darker the color is, like amber. Green bamboo carving makes full use of the difference in texture and color changes. It uses the method of leaving all, more, less or no green bamboo to divide the layers, forming a natural fading effect from dark to light. The light and dark, thick and thin are applied according to the scene. "Shading carving technique" is another feature of the bamboo carving technique in southern Anhui. The main pattern of the work is left in green, the first layer of the bottom pattern is not left in green, the second layer of the bottom pattern shows the texture, and the third layer of the bottom pattern has a darker texture, thus forming a three-dimensional pattern. The color of the pattern transitions naturally from dark to light.
