An artist works on the design of an inkstone at a local inkstone manufacturer in Shexian County, east China's Anhui Province, June 23, 2020. Inkstone is one of China's traditional "Four Treasures of the Study", together with ink brush, inkstick and Xuan paper. It is used to make liquid ink for calligraphy and painting, by grinding inkstick while mixing it with water. As one of China's four famous inkstones, the She inkstone is made from raw materials with a fine texture, and is often decorated with exquisite carvings. The traditional making technique of She inkstone has been recognized as a national intangible cultural heritage. (Xinhua/Liu Junxi)
