Wu Desheng, a famous Yixing Zisha pottery store in the Republic of China, was opened by Wu Hanwen in Yixing County, Jiangsu Province in 1916. After 192, Jinding Trademark was launched and gradually developed into a company business model. In 1925, a semicolon was added in Shanghai, and it stopped operating in 1939 due to the outbreak of War of Resistance against Japanese Aggression and other reasons. Subsequently, Jinding Trademark was no longer used. Wu Hanwen, the owner of the store, is good at carving, and many of his works are signed "Gang Tao", "Qi Tao", "Qian Tao" and "Songhexuan". During more than 2 years' operation, most of the purple sand produced by Wu Desheng was participated by famous pot makers and ceramic artists at that time.
