There are several kinds of compasses in Li Juming. What kind of geomantic compass is made of?

As the founder of Yang Gong geomantic omen, Yang Gong not only established a complete geomantic omen theory, but also reformed the geomantic omen compass reasonably.

The Twenty-four Mountain Plate was created by Yang Gong. Before Yang Gong, there were no complete twenty-four mountain plates, only eight diagrams plates and twelve branches. Although the compass of the Han Dynasty also has the marks of "Eight Diagrams", "Earthly Branches" and "Heavenly Branches", it does not divide the degrees equally, but divides the heavenly stems, eight diagrams and twelve earthly branches into three layers with different degrees. Yang Gong rearranged it, and completely distributed Bagua and heavenly stems and earthly branches on the plane, which was an epoch-making creation.

The astrolabe of the Twenty-four Mountains, or the Seventy-two Dragon Pan, was created by Yang Gong in his later years. Through long-term exploration and practice, Yang Gong found that Yin-Yang and Five Elements generally exist in all directions, and the distribution of Yin-Yang and Five Elements is determined according to the Eight Diagrams and Five Elements, which is inconsistent with the actual situation. It's too rough to use yin and yang dragons as dragons. Through repeated research, twelve dominant heavenly stems are used to express the five elements of the dragon, which is called "upside down" five elements. In the "Green Capsule Austrian Language", "upside down, there are jewels on the 24 th Mountain; On the other hand, there is a fire pit on the twenty-fourth mountain, and this "upside down" refers to the seventy-two dragons in Yin Na's five lines.
