An introduction to the history of ancient books in copperplate printing

The most famous printing activity of Wuyingdian was to print ancient and modern books with copper movable type in the fourth year of Yongzheng (1726), and the other time was to print Wuyingdian Juzhen series with wood movable type in the Qianlong period, which were also the two biggest printing activities of the Qing government.

Sixty-four volumes of The Integration of Ancient and Modern Books, each with 10,000 volumes and 40 catalogues, * * * has printed 5,020 volumes. Printing such a large encyclopedia is the first time in the history of our country, and because it is printed with copper movable type, it is a great event in the history of printing. The collection of ancient and modern books is arranged by category, and the collected materials are extremely rich, most of which are whole paragraphs, whole articles or whole works.
