As an encyclopedia, what knowledge does Yongle Dadian contain?

Speaking of Yongle Grand Ceremony, many people don't really understand it, but from another angle, people will understand it. That is to say, some of the SikuQuanShu that we are using now are actually included in Yongle Dadian. Just because of the war and some human factors, the Yongle Grand Ceremony was not completely preserved, leaving only some fragments. If it can stay, it must be a great cultural treasure of our country.

The Yongle Dadian was first revised in the Ming Dynasty, when the emperor was far-sighted and revised this document. It is to classify and collect all the classic documents before and after the Ming Dynasty for future reference, and it involves a wide range of knowledge, such as astronomy, medicine, history, divination, agriculture and so on. We now have a lot of professional knowledge that can be learned from the Yongle ceremony.

The wisdom of the ancients should not be underestimated, and the status of this book at that time was also very high. The emperor will carry it with him and take it out to check anything. It is said that after the death of the emperor at that time, the original Yongle ceremony had been taken away for burial. The remaining volumes are actually manuscripts, but it would be great if all the manuscripts at that time could stay.

Later, due to the invasion of Beijing by the British and French allied forces, many parts were lost after the ceremony, leaving only some fragments, but only these fragments benefited people in various fields of modern science. Generally speaking, Yongle Dadian is an encyclopedia, covering a wide range, from astronomical geography to crops.
