Abstract: The author of this paper has discovered a copy titled as Kai Cheng Ji Yao kept in Zhejiang Library. Although the copy was transcribed by Han Yingbi, a famous bibliophile in modern Shanghai, it showed that this is in fact an unpublished work by Xu Guangqi (Paul Xu). The content of Kai Cheng Ji Yao can be divided into two parts. The first part is about some of the traditional folk crafts in Chinese, and the second part is about some new knowledge of science and technology from Europe of which some was surely introduced by Matteo Ｒicci,while others were introduced by other European missionaries. This recently discovered work provides a new document not only for further exploring Xu Guangqi’s achievements in science and technology, but also for the in-depth research of the traditional Chinese science and technology, especially the European knowledge introduced by the missionaries in the late Ming Dynasty. At the same time, this copy is also contributive to the study of Han Yingbi and his private library.
Key words: Kai Cheng Ji Yao; Xu Guangqi; Matteo Ｒicci; Han Yingbi; Yao Yuanchu.
