Yixing zisha pottery is a remarkable treasure in the cultural and artistic heritage of the Chinese nation. In the long river of Chinese ceramic history, based on excavations of ancient kiln sites, it can be traced back to the mid-Northern Song Dynasty, with a history of approximately one thousand years. It has gained renown both in China and abroad for its unique ceramic art style. The art of zisha pottery has developed alongside the evolution of human cultural life and material civilization, gradually reaching maturity. Over the long course of history, zisha pottery art in the Song Dynasty was still in its embryonic stage, with products generally being rather crude. By the mid-Ming Dynasty and thereafter, famous masters emerged in abundance, with talented artisans appearing in every generation. Notable Ming Dynasty masters include Gong Chun, Shi Dabin, Li Zhongfang, Xu Youquan, Chen Zhongmei, and Chen Yongwei. In the Qing Dynasty, there were renowned craftsmen such as Chen Mingyuan, Sheng Si, Chen Jueshang, Shao Xumao, Chen Mansheng, Yang Pengnian, Shao Daxiang, and Shao Youlan.
