Is a family, and "Jianshan" is a famous model for making kilns in the national porcelain workshop in the Tang Dynasty. In the early years, Tangguo Porcelain Factory established the Jigong Kiln Jianzhan Ceramics Research Institute in Shuiji Town, Jianyang, with Master Wu, the first intangible inheritor of Jianzhan manufacturing technology, as the main manager, and the bottom of his early works was Jigong Kiln. Mr. Gan Jianhua, executive vice president of Jianzhan Association, wrote an inscription for Jigong Kiln, "Jigong Jianshan Stand Firm and Go Forward", praising its artistic spirit of standing on its roots and being brave in persistence. Many years ago, Jigong Kiln ranked in the top three among the top ten brands of Jianzhan, and it was the old kiln mouth in the field of Jianzhan. 20/kloc-in March, 2006, Jigong Kiln and Wang Laoji, a time-honored Chinese brand, entered the dialogue meeting of NPC deputies. Because the trademark registration of Jigong Kiln was unsuccessful, it was renamed Jianshantang. Later, according to the craft and style of the works, three series of works, Jianshan Kiln, Jianshan Burning and Jianshan Ware, were launched.
