The "Xubianhu" form has been applied to the making of clay teapots since the late Ming dynasty. The Shanghai Museum houses a "Xubianhu" with a seven-character seal script inscription reading "Yuanyuantang Collection, Made by Dabin." This teapot has an elegant form and magnificent bearing, making it an exceptional masterpiece among extant "Xubianhu" teapots. *Xubian*, also written as *shubian*, originally described flat objects resembling books in shape. In the Dingshan dialect, "shu" (book) and "xu" (empty/void) are homophones, so "xubian" became the more commonly used term. In traditional Yixing purple clay hand-crafting techniques, the body of the "Xubianhu" is shaped by beating with a paddle, making it quite difficult to form. As the trade saying goes: "The flatter the form, the harder it is to make." The first "Tall Xubianhu" was created in the early 1990s. Because the overall capacity was relatively small, approximately 380 milliliters, in order to allow tea leaves to tumble freely during brewing, Gu increased the height of the body based on the traditional "Xubianhu" form. The lid rim transitions to the spout opening with a straight edge, and the foot ring also takes a linear form, giving it a strong sense of antiquity. The second "Tall Xubianhu" was created in 1993 for the Yixing Purple Clay Pottery Fine Works Exhibition in Taiwan. Compared to the first version, the lower belly was drawn inward, giving the body more tension and dynamism. At the same time, rim lines were added to the lid and mouth, and a base line was added to the foot ring, creating visual harmony among these elements. --- [1] Gu Jingzhou, ed., *Appreciation of Yixing Purple Clay Treasures* (Hong Kong: Joint Publishing (H.K.)
