It is about the grain production of Yongle Grand Ceremony.

Yongle Dadian was compiled in Yongle period of Ming Dynasty. Jie Jin, chief editor of the Cabinet, edited a China classic "The Grand Ceremony", formerly known as "Documentary Masterpiece". It is an encyclopedic collection of China literature, with 22,937 volumes (60 volumes in the catalogue) and 1 1095 volumes, with about 370 million words, which brings together seven or eight thousand ancient and modern books. Encyclopedia Britannica called China's Ming Dynasty book Yongle Dadian "the largest encyclopedia in world history".

Yongle Dadian contains more than 8,000 kinds of ancient books from pre-Qin to early Ming Dynasty. In addition to masterpieces and subsets of history, it also includes various works such as philosophy, literature, history, geography, religion, medicine and divination. It is the largest encyclopedia in the history of China, more than 300 years earlier than the famous Encyclopedia Britannica.

The contents of Yongle Dadian include poetry, drama, monks, Taoism, medicine, technology and so on. Among them, Yongle Dadian also contains many precious books that have been incomplete or lost in later generations, such as Xue's A Brief History of Liao Dynasty and Shui Jing Zhu in Song Dynasty. The quoted materials are completely copied from the original text, so many precious documents can be preserved.
