What do you think of the twelve immortals who are not marked on the geomantic compass?

The contents of the compass are displayed in layers. There are 40 floors in total, and the Qing Dynasty booked 13 floors. The most complete compass is twelve immortals. Most of the basic knowledge of geomantic omen needs to be thoroughly mastered. If they are all marked on the compass, the contents of the compass are too complicated and bulky. In modern times, the twelve gods of immortality are called the realm of the birth and death of the five elements or the realm of the birth and death of all things, including the four-game immortality, the yang-dry immortality, the yin-dry immortality and so on. These contents are explained in detail in related books, so it is impossible to repeat them here.
