What is Feng Shui knowledge?

Earth-qi is the essence of heaven and earth,

The earth is the mother of all things,

It has a nourishing effect on all living things on the earth and belongs to the category of "generating everything".

Man and nature are an inseparable whole, so we should absorb the "weather" and inherit the "local flavor". Nature's sunshine, wind, rain and lightning, and even the microwave radiation of the universe all belong to the category of "weather". "Ground gas" includes all information such as air pressure, latitude, humidity, and odor emitted from the ground. If it is explained by modern science, simply speaking, "geogas" actually refers to the earth's magnetic field, but there is no geomagnetic theory in ancient times, and it can only be summarized by "geogas".

Therefore, the earth's atmosphere is invisible.
