Understanding of geomantic omen
China ancients called geomantic omen geomantic omen, also called geography. Let's read together: geomantic geography. We might as well explain it this way: the research and analysis theory of geomancy (observing the sky), geomancy (geodesy), wind (airspace), water (hydrology and water quality) and land (topography and geology).
On the earth, what is the largest substance, that is, wind, water and soil. What is the most basic substance for human existence? It is also wind (gas), water and land. Please don't forget the "land" when talking about Feng Shui.
On the earth, except for the matter from celestial bodies, almost all matter is all things, including human beings. It can be seen that the ancient geomantic omen refers to all the substances on the earth, and geomantic omen is a theory to study the microscopic substances (air, water and soil) and the macro environment (heaven and earth) on which human beings depend for survival and development.
According to the ancients' cognition, except land and water, everything else is space, and there is only wind in space. The ancients believed that wind, space and sky were linked. The wind in Feng Shui is not only air, but also space and sky.
