1. Yongle Dadian is the first encyclopedia written by Amin Emperor Judy in China. He has asked Yao to preside over the compilation, including the subset of ancient books, astronomy and geography, yin and yang divination, medical skills, drama, Taoist interpretation, industry and agriculture, etc. From the first year of Yongle to the sixth year of Yongle, the manuscript was finally completed and copied, which was called by the Encyclopedia Britannica. It was originally named "literary masterpiece", and later Ming Chengzu personally wrote the preface and named it "Yongle Grand Ceremony". The book has 22,877 volumes (60 volumes in the catalogue, 22,937 volumes in * * *), 1 1095 volumes, about 370 million words, and 7,000 ancient and modern books are collected.

The aim is to "compile all the hundreds of books on classics and history since the book was made, as for astronomy, geography, yin and yang, medical divination, Buddhism and Taoism, and the number of skills." At first, it was compiled by Jie Jin (scale: 147 people), and a year later it was compiled into a literary masterpiece. However, I was very dissatisfied after seeing it in person and appointed Yao as the producer. At the same time, the establishment team was expanded to 2 196 people (more than 3,000 people in total), and it was finally decided in the fifth year of Yongle (1407), Judy herself. The whole book was copied in the sixth year of Yongle (1408).
