Geomantic omen is scientific, and the land of geomantic omen is not found out of thin air, but depends on the surrounding geographical conditions. For example, the tiny terrain with high surrounding and low middle is the favorable terrain valued by geomantic omen, surrounded by mountains and lush in the middle, which is very charming; For another example, the inward basin with high terrain in the north and low terrain in the south, sunny and cool, also hides wind and gathers gas. According to the theory of geomantic omen, this position is the result of the combination of topography, climate and ecological environment.
In a certain place, if the grass tree germinates and grows late in spring and leaves fall late in autumn, it means that the airflow between east and west is not smooth in this place; If there are mountains in the north and mountains in the south, the terrain is not ventilated, and the first two are not good places for feng shui. Usually good feng shui must ensure that there is sunshine and the wind is unimpeded. If the north is high and the south is low, it is a good place to get as much sunshine as possible. If both sides are slightly higher than similar "handrails", it is a veritable land of feng shui.
Water is a necessary substance for human survival. Without water, nothing can survive. In ancient times, people liked to live where there were mountains and water. When there are mountains, they can rely on them to enjoy the scenery. When there is water, they can also grow crops. Where there is water, they naturally form one of the foundations of the land of feng shui, but they are just "heartless" When looking for "water", floods will occur if the water is too strong. It should be emphasized that the water in the land of geomantic omen is flowing water, which can be used for people to drink and live, rather than a stagnant pool or water that cannot be used for people to live.
Geographically speaking, there are mountains behind to block the cold wind in the north, and there is water in the south to enjoy the cool wind in the south in summer. Can also be used for irrigation, boating, breeding, sunny, easy to get good sunshine. The gentle slope hills are not affected by floods, and the surrounding vegetation is lush, which can not only conserve water, maintain vents, but also adjust the climate. Combine these different characteristics of the environment to create an organic ecological environment, which is the geomantic omen of ancient buildings.
Generally speaking, when a mountain comes, it is best to have a "node" where it bends, is surrounded and meets the plain. Feng Shui tells people in a quasi-philosophical way that it is better to have water on the back of the mountain, and creatively puts forward many aesthetic concepts such as "being surrounded by love". After all, the land of geomantic omen is limited, and obviously it is impossible for everyone to find it. According to Bian Xiao, it is best to spend more time on how to improve their Feng Shui.
