Historical origin:

In the first year of Yongle (1403), Judy made up her mind to write a masterpiece of national prestige. 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. But after reading it, he was very dissatisfied and appointed Yao as the supervisor. 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).
