In Yang Gong's geomantic omen, what does the dragon mean?

There are three elements in the essence of ancient geomantic omen: mountain, wind and water, which play twists and turns like a dragon. Therefore, ancient tombs are often in the mountains, where mountains gather gas and are surrounded by mountains. The gas is dead and can't be used by people, so where there is wind, the wind will drive the airflow to move, but the wind can't control the direction, so it is called geomantic omen! But now many so-called masters, because they seek ill-gotten gains and cheat money with geomantic omen, even these masters often appear in magazines and TV. In fact, they are simply lying. Their geomantic omen is the ancient people's planning of the Yin house in the Book of Changes, and the planning of the Yang house is based on that theory. This kind of people really make fun of their ancestors' culture again, which is naked trampling, because the landscape layout of Yang Zhai is planned in the Book of Changes. And their ignorance is purely for their own preferences. That geomantic deception not only deceives people, but also makes many people who don't understand the essence of China culture blindly label China culture as superstitious. Those so-called Feng Shui masters really don't deserve to be China people.
