The Gǔjīn Túshū Jíchéng ("Complete Collection of Illustrations and Writings from the Earliest to Current Times"), a vast encyclopedic work written in China during the reigns of Qing emperors Kangxi and Yongzheng, completed in 1725, had been headed initially by scholar Chen Menglei, and later by Jiang Tingxi.

One of the Yongzheng Emperor's brothers had patronized the project for a while, although Yongzheng contrives to give exclusive credit to his father Kangxi instead.

It contains eight hundred thousand pages and over one hundred million Chinese characters.

Topics covered include natural phenomena, geography, history, literature and government.
