Is the Book of Changes witchcraft? What do you think, saints?

It is true that the Book of Changes is a divination book. It is the source of China culture, and it has influenced a hundred schools of thought and Chinese medicine.

Personally, although it is a book of divination, it is reasonable from image to righteousness, not nonsense.

As for the theory of Yin-Yang, Five Elements and heavenly stems and earthly branches, if we look at the application of these ideas in traditional Chinese medicine and astronomy, we will know that they are not made up casually, but no one can prove them with the present science.

Personally, I think these are the experiences of the ancients. Whether it can be said to be "truth" is still inconclusive.

I suggest you read nan huaijin's Miscellaneous Notes on the Book of Changes and Biography of the Book of Changes.
