Introduction of sixteen-character yin-yang geomantic occult technique

The first wonderful book in the world, The Secret of Yin and Yang Sixteen-character Feng Shui, was created by a captain who touched gold in the Qing Dynasty, among which Yin and Yang Feng Shui was one of them. Although Yin and Yang Sixteen-character Geomantic Mystery is called sixteen characters, it should be sixteen volumes, and each volume is represented by one word in ancient Sunday divination, so it is called sixteen characters. Note: This book is written by a ghost blowing a lamp. The real world does not exist. So don't think you can find treasure everywhere, but it's nothing.
