There is a saying: "the method of feng shui, first get water, then hide the wind." He also said: "Mountains divide water, plains divide wind"; "Tibetan wind is the highest in the mountain and water is the first in the plain."
For example, the Book of Burial says: "Buried people are angry", "Qi is dispersed by the wind ..... the ancients gathered for a long time, but stopped it", "Qi remains and stops, and everything turns to the ground".
It can be seen that "hiding the wind" is to achieve the purpose of "gathering gas".
The accumulation of Tibetan wind and gas is rooted in the understanding and requirements of choosing settlement conditions. In fact, regardless of the flat and high mountains, in the era when "thatch, branches, bamboo bundles and vines" are the main building materials, the ability of "thatch, branches, bamboo bundles and vines" to resist natural cold is extremely limited, so it is the most important thing to choose a sheltered and warm terrain. With shelter and warm terrain, everything becomes prosperous, orderly, relaxed, safe and auspicious. Today, although the development of science and technology has made it obvious that building materials have the ability to overcome and resist natural disasters, people still appreciate the concept of storing wind and gathering gas.
The land of "hiding wind" and "gathering gas" should be protected by winding mountains or winding around them. The crowd pushes forward, without coercion, and can gather without being abrupt. Come to the mountains to stop gathering, and yin and yang are in harmony. Thick layer, deep water, lush vegetation. In a word, this is an angry place with mountains, water, mountains and rich vegetation.
An important function of the ideal model of geomantic omen is to avoid the wind, or to avoid the wind, and the ultimate goal is to keep the vitality of the small environment (or gas field) from losing. Because anger is the root of all things, the loss of anger means the loss of "vitality" in the environment around the cave field, and the loss of vibrant environment is the performance of "disaster"
