The hidden wind in feng shui is to leave anger in the cave, so as not to let the strong wind wash away the cave and make the anger drift away. In geomantic omen, qi gathers in water and wind disperses in wind. Therefore, it is important to get water, but if the cave is not sheltered from the wind, the anger will be dispersed by the wind.
Guo Pu said in "Buried Scriptures": "In the land with high ridges, the sky is overcast from top to bottom, and the air is full of dew. I am most afraid of cold and easy to drift away. If people live in the depths of the secret room, with a little gap ventilation and proper shoulders, they may get sick. Therefore, it is required to close the wall to make the gas gather. " Therefore, the best layout of Tibetan wind is that all directions are close and complete, which can shelter and condense life.
Generally speaking, the theory of Tibetan style is mainly aimed at mountainous areas. For plain areas, vitality sinks into the ground and rises from below, not afraid of being blown away by the wind. Even if the cave is empty on all sides and has no cover on all sides, it will not hinder the cohesion of vitality. It is based on Tibetan style, and only on mountain ridge caves.
