This has been discussed in detail in the article, which also focused on Gu Jingzhou's views on the Gong Chun teapot. Particularly during his serious illness, he explicitly told his student Pan Chiping that, including the piece in Shanghai collector Shi Zhenchang's collection, he had seen thirteen "Gong Chun teapots" in his lifetime, all of which he believed were made by Huang Yulin in the late Qing Dynasty, not by Gong Chun himself. In 1983, when Shi Zhenchang's second son brought the teapot requesting Master Gu's authentication, the young Mr. Shi found it difficult to accept Gu Jingzhou's conclusion. To achieve a direct and clear demonstration, Gu Jingzhou had "Wu Qunxiang fetch another 'Gong Chun teapot' made by Huang Yulin from the factory exhibition room, and through comparing the consistency in technique and tool usage, Mr. Shi was finally convinced."[1] When we revisit this story today, it is certainly not to investigate the true authorship of these "Gong Chun teapots," but rather to learn from the attitude and techniques that Gu Jingzhou maintained in authenticating Yixing teapots, and apply them to our appreciation and authentication of Gu Jingzhou's Yixing works today. ## Where There Are Objects, There Are Standards: Striving for Excellence Gu Jingzhou was not only a master craftsman but also an expert authenticator. His authentication was based not only on his mastery of Yixing pottery's cultural and historical knowledge, but also on the experience he accumulated from participating in antique reproduction work in Shanghai during the Republican era. Gu Jingzhou had his own principled views on authenticating Yixing teapots: > Identifying the authenticity of Yixing teapots is like authenticating calligraphy and painting. First, enhance rational understanding—rationality means cultivating one's scholarly accomplishment to elevate aesthetic perception. Second, engage in extensive exchange, mutually appreciating masterpieces by certain famous artists to enhance sensibility, exploring and understanding the stylistic forms, technical methods, artistic strengths, and habitual use of clay materials and colors by certain renowned makers, as well as the specifications and characteristics of their seals. Grasp the key evidence and gradually accumulate experience. Those with discerning eyes will naturally find it easy to distinguish authenticity... What is genuine was born genuine; what is fake can never become real. --- [1] Pan Chiping, "Recognition Extended from the Gong Chun Teapot," *Yixing Zisha*, Issue 12, 2010.
