Bottom line introduction: Jinding trademark, namely Wudesheng Purple Clay Pottery Shop (also called company or shop) in the Republic of China, was established by Wu Hanwen in the fifth year of the Republic of China (1916). The store is located on the edge of Jiaoqiao Bridge in Yixing County. In the early days, the seal was used as a small square seal in the Yangwen script of "Wu Desheng", with a bottom cover and use. Later, it will be printed as the "Wu Desheng System" of the Yangwen Shuda Dafang Chapter. In the middle period, the seal was used as Da Yuan Zhang Yang Wen, and the calligraphy was "Wu Desheng System" and "Yixing Wu Desheng System". By the late 1920s, store owner Wu Hanwen established the famous trademark "Jinding Trademark" for the "Wu Desheng" store name. The "Jinding Trademark" is printed with a tripod as the pattern in the center, and the four corners are printed with the "Jinding Trademark" in Yangwen regular script, which is the exclusive stamp for ordering pots for the "Wudesheng" store number. In the later period, Wu Hanwen also stamped the seal "Songhe Xuan" in Yangwen regular script on the refined pot. The stamps of "Wu Desheng" and "Jinding Trademark" are stamped on the bottom of the pot, and the lid is usually stamped with the small square seal of the pot maker. At that time, there were Yan Ru, Chu Yinlan, Wang Xichen, Feng Guilin, and others who specifically made purple sand tea pots for Wu Desheng. Artists who specifically engraved Wu Desheng were Ren Ganting, and those who often ordered blanks were Yu Guoliang, Cheng Shouzhen, Zhu Kexin, Wang Baogen, Wu Yungen, Wang Yinchun, and others. In the 14th year of the Republic of China (1925), Wu Hanwen established the "Wu Desheng" branch in Shanghai, mainly selling purple sand products. Wu Hanwen also used the "Wu Desheng" style in the early days of his own tea pots. After the outbreak of the War of Resistance Against Japan, "Wu Desheng" went bankrupt, and the "Wu Desheng" and "Jinding Trademark" were used for printing until the end of 1939.
