Entrusted by Lin Zexu, Wei Yuan wrote a comprehensive work on world geography and history. Based on the Annals of Sizhou compiled by Lin Zexu with less than 90,000 words, it expanded other documents, books and periodicals collected at that time and many papers written by Wei Ziyuan. It was first carved in the 22nd year of Daoguang, with a total of 50 volumes. In the twenty-seventh year of Daoguang, the supplementary publication was engraved as sixty volumes. Subsequently, Xu Jishe compiled the Biography of Ying Huan in the 28th year of Daoguang, compiled 100 volumes and published them in the world in the 2nd year of Xianfeng. The book describes in detail the world geography, historical and political system, local customs, customs and habits of various countries, advocates learning from western science and technology, and puts forward the central idea of "learning from foreigners to control foreigners". This is an epoch-making masterpiece.
