Cover of *Appreciation of Yixing Zisha Pottery* Gu Jingzhou and his group also visited the Art Museum of the Chinese University of Hong Kong, the Hong Kong Museum of Tea Ware, and the "Min Chiu Society" private club. The third visit was in 1989, again at the invitation of Jinfeng Company to visit Hong Kong and participate in trade negotiations. In early 1992, Gu Jingzhou, together with Xu Xiutang and Li Changhong, completed *Appreciation of Yixing Zisha Pottery*, which was publicly published by Joint Publishing (Hong Kong). This book contains detailed materials, clear images, and authoritative scientific textual analysis, making it an important reference work for zisha connoisseurship and collecting. The abundant materials and images in the book have been widely cited by various subsequent publications. To this day, this book remains a classic among reference works on zisha pottery. As a transit point for zisha trade between mainland China and Taiwan during the early period of reform and opening up, Hong Kong's trading business brought a large number of exquisite Yixing zisha pieces to the treasure island of Taiwan. With the gradual relaxation of cross-strait policy positions and the deepening of民间 exchanges, on October 21, 1993, the 78-year-old Gu Jingzhou visited Taiwan with the "Yixing Ceramic Art Exhibition" delegation. Upon setting foot on the treasure island, Gu Jingzhou was warmly embraced by countless teapot enthusiasts. During the ten-day exhibition, visitors streamed in continuously, further promoting the zisha collecting fever on Taiwan island. Facing such overwhelming enthusiasm, Gu Jingzhou remarked with emotion: "At the advanced age of eighty, I have fulfilled my wish and personally experienced in Taiwan the deep affection friends have for my zisha work and for me personally. I must say, thank you!"
