What does the Yongle ceremony include?

The contents of Yongle Dadian include classics, history, poetry, book collection, astronomy and geography, Yin and Yang medicine, divination, interpretation of Tibetan scriptures, drama, science and technology, agriculture and so on, covering thousands of years of intellectual wealth of the Chinese nation.

The purpose of Yongle Dadian is that "all the books that have been a subset of the Classic since the bookmark, as for astronomy, geography, Yin and Yang, medical divination, Buddhism and Taoism, and skills, have been compiled into one volume". At first, Jie Jin presided over the compilation, 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 supervisor. At the same time, the editorial team was expanded to 2 196 people, and Yongle finalized it in five years. Judy personally prefaced it and named it Yongle Dadian. The whole book was copied in Yongle six years.

Extended data:

When the Yongle Grand Ceremony is completed, there must be many styles and types of illustrations. If the illustrations of Yongle Dadian are compiled separately, it will be a great display of ancient civilization.

Ji Xiaolan, a great scholar in Qing Dynasty, once said in Notes of Yuewei Caotang that he was surprised to turn to the picture of the Song Dynasty weapon "Armbow" in Yongle Dadian when compiling Sikuquanshu.

According to the records in Yongle Dadian, the "arm bow" can stand on the ground, pull the trigger, and the arrow can penetrate the armor 300 paces away. It was very effective for the Song army to use the "arm bow" to deal with nomadic people.

Song Jun has strict military requirements on the use of this weapon, and it must not be lost or taken away by the nomads from the army. The Armbow was lost in Yuan Shizu. As a result, the "arm bow" eventually died with the Yongle ceremony.
