Sixteen-character introduction to Yin-Yang geomantic occultism, which sixteen characters are there?

these sixteen characters are: heaven, earth, man, ghost, god, Buddha, demon, animal, fear, town, escape, thing, culture, yin, yang and emptiness. This ancient book, which mainly records the geomantic omen of Yin and Yang, is all-encompassing, not only including geomantic omen and Yin and Yang, but also because it was written by a master who touched the gold, so it also covers a large number of descriptions of the shape, structure and layout of ancient tombs of various dynasties and generations, as well as all kinds of difficulties and dangers encountered by the gold-touching captains during the inverted bucket.

It can be said that The Sixteen-character Mystery of Yin and Yang Feng Shui is a genuine "Guide to Touch Gold and Flip Down", but this book is only a remnant, and the part of Yin and Yang has not been handed down, only the sixteen characters of Feng Shui.
