In total, twenty lectures were delivered, which became known in the industry as the famous "Twenty Lectures on Zisha Pottery." Pan Chiping carefully recorded notes from all the courses, which were reviewed and approved by Gu Jingzhou. Currently, eighteen of these lectures are preserved. Under Gu Jingzhou's guidance, the special training class "successively created works such as the Short Monk's Hat Teapot, Han Duo Teapot, Round Bell Teapot, Short Well Railing Teapot, Ru Ding Teapot, and Gongchun Tree Stump Teapot."[1] Through this systematic training, similar to an intensive workshop, not only did it establish a solid theoretical foundation for the students' zisha craftsmanship to reach new heights, but it also left a brilliant and glorious chapter for the prosperity and development of New China's entire zisha pottery enterprise. Several years later, a shocking incident occurred in Yixing. In responding to this incident, the skills the students had learned in the special training class were fully demonstrated. In March 1990, twelve sets comprising forty-one pieces, including Gu Jingzhou's "Tibi Tea Set," were stolen from the Yixing Ceramics Exhibition Hall. This occurred on the eve of Yixing's Second Ceramic Art Festival, and these works had been prepared as exhibits for the festival. To ensure the art festival could proceed as scheduled, Gu Jingzhou organized his students overnight to replicate these works according to each student's specialty. He provided the original dimensions of his works to the students, explained the structural key points and technical difficulties of each piece, personally supervised and gave repeated guidance throughout the process, and finally stamped "Supervised by Jingzhou" and his own seal on the bottom of the completed teapot blanks. The students who participated in the replication all vividly remember this experience. Zhou Guizhen recalled: "When the exhibition hall was burglarized and there was an urgent need to remake the pieces, Master Gu asked me to make two each of the Imitation Drum Ruyi and Three-Line Teapots. Each teapot was stamped with Jingzhou's small seal and marked as supervised..." Gu Shaopei, who was assigned to replicate the "Xuehua Teapot," also recalled: "At that time, under the master's personal guidance, we completely followed the original work to prepare the templates and he transmitted the secrets of the techniques..." In Gu Shaopei's notebook, there is a complete record of the revision suggestions that Gu Jingzhou made on March 25, 1990, in his workshop regarding the sample "Xuehua Teapot" he had replicated: > 1. The body cylinder is generally acceptable, pay attention to the fullness of the lower belly; > 2. The shoulder is slightly flat, it can be raised a bit; --- [1] Xu Xiutang and Shan Gu, *Zisha Master Gu Jingzhou* (Shanghai: Shanghai Ancient Books Publishing House, April 2013 edition), p. 185.
