What is subtraction geomantic omen?

Subtractive geomantic omen, also known as simplified geomantic omen and dynamic geomantic omen, is a life environmentology which takes innate gossip and the acquired Eight Diagrams as the body, uses the Eight Diagrams Palm and the Ten Eight Diagrams, and the body and the use are mutually changing and rooted, grasps the mysteries of the past, present and future, and drives away good fortune and evil spirits.

Subtraction geomantic omen is relative to addition geomantic omen, which is mainly different from the popular addition geomantic omen from two aspects: the basis of argument and the means of solution. The theoretical basis of "additive geomantic omen" is static gas field law or mistaking static gas field law for dynamic gas field law. The solution based on this wrong argument is naturally incorrect, so there are great problems in the geomantic pattern adjusted by additive geomantic omen theory, and ineffectiveness or instability is a common problem.

Moreover, there are serious mistakes in the establishment of "twenty-four mountains and five elements" in Additive Feng Shui, and there are mistakes in such a key academic issue, and its effect can be imagined. Why have scholars been opposing and criticizing Feng Shui for thousands of years? The main reason is that the popular Feng Shui theory is imperfect, complicated and difficult to master, and the real knowledge has not been carried forward, resulting in the so-called "feudal superstition" situation today.
