Is the three-in-one geomantic eight-point method a three-way puzzle?

Is the three-in-one geomantic eight-division method very confusing? The three-division method originated from the Great Plains without any obstacles, and I have never visited the Great Plains (such as the North China Plain) on the spot. How about the accurate measurement of ternary method? However, in mountainous and hilly areas, the ternary method is not accurate when the topography is irrelevant. As long as the terrain is suitable for a certain purpose, the ternary method is considered bad and fierce, such as the method of going up the mountain and launching water, which has no described facts and is the opposite result. My point is that the ternary method only manages the integrity of the theory and needs further study. Trinity is not a combination of eight, but a combination of longevity, prosperity and tomb across eight. Life, honor and tomb are the theory of Theory of Three Represents stage in the development process of a complete thing, so they are combined with eight.
