Gu Jingzhou began his journey into Yixing pottery at the age of 17 under his grandmother's influence, immediately displaying exceptional natural talent. He later honed his skills by studying with fellow townsmen and accomplished artisans such as Chu Ming, earning recognition throughout the region. In 1936, he traveled to Shanghai to participate in the wave of antique reproductions, meticulously studying historical masterpieces. This experience not only broke through the geographical limitations of small Yixing, but also refined his craft through the process, forming a distinctive artistic style. During this period, Gu Jingzhou's seal marks on his Yixing teapots included rectangular seal impressions in regular script reading "Gu Shi" and "Jing Ji" used on handles, as well as personal name seals such as "Jingzhou," "Gu Jingzhou," and "Shou Ping" used inside lids and on pot bottoms. He also employed studio hall marks including "Mo Yuan Zhai Yi Tang Zhi" and "Zi Yi Xuan," which serve as important testimony to Gu Jingzhou's early artistic debut and vigorous development. Among the studio hall marks, the rectangular relief seal in seal script reading "Mo Yuan Zhai Yi Tang Zhi" was used on horizontal teapots and vermillion clay *Hehuan* teapots, paired with the handle seal "Jing Ji," creating an elegant and refined effect. The "Mo Yuan Zhai Yi Tang Zhi" seal was not exclusively Gu Jingzhou's personal mark; it also appears on horizontal teapots with the handle seal "Fu Ji." Another studio hall mark, "Zi Yi Xuan," first appeared on a melon-shaped teapot, with "Zi Yi Xuan" impressed on the bottom, "Jingzhou" on the lid, and an inscription carved on the body reading: "Correspondence with cypress leaves sent by immortals, flavor as pure as the Prefect of Jiangcheng. Autumn of Bingzi year." This indicates that the "Zi Yi Xuan" seal was in use by 1936 at the latest. Later, to help support the livelihoods of his neighbors Wang Yinchun and Shen Xiaolu, he also lent them this seal for their use.
