The translation of western scientific and technological works is the most obvious feature of the change and development of scientific and technological classics in Ming and Qing Dynasties. Early scientific and technological translations included the first six volumes of Geometrical Elements translated by Xu Guangqi and Italian missionary Matteo Ricci, the written work Wen Tong Yi Zhi translated by Li Zhizao and Matteo Ricci, and the mechanical work Illustrated by Wang Zheng and Swiss Deng Yuxin. The almanac of Chongzhen, which was officially compiled in the late Ming Dynasty, and the comprehensive theory of mathematics, which was officially compiled in the Kangxi period of Qing Dynasty, are two large almanac classics.
