After the founding of New China, Gu Jingzhou actively participated in establishing the pottery production cooperative, serving as a member of the cooperative's production management committee and technical advisor. He worked diligently and conscientiously, not only creating a large number of excellent works with his exquisite skills and rich accumulated experience, but also tirelessly teaching others, passing on the Yixing pottery techniques that had been formed from the Ming and Qing dynasties through the Republican period. During his time at the cooperative, in addition to stamping his own name seal inside the lid of works created by Gu Jingzhou, he also stamped the seal "Produced by Yixing Tangdu Pottery Production Cooperative" on the lid. In the late 1950s, although Gu Jingzhou suffered from false accusations of being a "rightist典型," he continued as always to devote himself wholeheartedly to the production and technical research at the Yixing pottery factory, using the seal "Mansheng Taoyi" (which had been used earlier for fine works) on prototype works from this period. Examples include: the "Awakening Bell Set," *Gao Sanxian Coffee Set*, and others. Works of this type often used in combination the "Gu Jingzhou" yang-wen square seal or the "Jingzhou" rectangular seal inside the lid. --- [Note: The text appears to be incomplete at the bottom with fragmentary characters that don't form complete sentences: "寿星" (Longevity Star), "壶底部签款" (signature on the bottom of the teapot), "明" (Ming), "评" (comment/critique), "小下" (small below), "冉" (a surname).
