Excuse me, what are the three ancient mysterious books?

There are three major mystical books in ancient China: one is the Yellow Emperor's Internal Classic, the other is the Book of Changes, and the third is the Classic of Mountains and Seas. The so-called Three Mysterious Books

were things that were impossible to write with the knowledge, skills and tools at the time, but we didn't know how to write them.

The "Huangdi Neijing" is the foundation of traditional Chinese medicine and is still brilliant today. The "Book of Changes" made Feng Shui a reality, while the "Shan Hai Jing" was written at the time.

There were no satellites or modern surveying and mapping tools. Under the circumstances, the vast territory of the north, south and north is basically accurately depicted.

In addition, there are three major metaphysics in ancient China: one is the theory of traditional Chinese medicine written by the "Huangdi Neijing", the second is the wind

water described in the "Book of Changes", and the third It seems to be something related to fortune telling, I forgot about it. Anyway, after the founding of the People's Republic of China, only traditional Chinese medicine was able to develop legitimately, and the rest were dismissed as feudal superstitions.
