People's attitude towards the wind is twofold. In dry and hot climate, cool wind with a certain humidity is very popular, while wind that is too cold, too hot, too strong or too dusty is not popular. People are often willing to accept the summer breeze, strengthen convection and heat conduction, and accelerate the heat dissipation of the human body; People in wet areas hope that wind energy will take away unpleasant moisture. Therefore, when choosing a construction base, it is necessary to avoid overheating, supercooling and strong wind, but also to have a certain wind speed.
3. You can't choose a base in the level terrain. Under this topographical condition, the airflow concentrates to the mountain pass, forming a jet with dense streamline, and the wind speed doubles to become the tuyere. Never! Ridges and hilltops, where the wind speed is usually high; At the same time, it is not suitable to choose places such as deep valleys and low-lying valleys with high frequency of static wind and breeze. The wind speed of these landforms is too small, which is easy to cause stagnant and dull covering, serious air pollution and diseases. In short, it is necessary to choose a place where the dominant wind blows frequently in summer and is less affected by the dominant wind direction in winter, and there is no air pollution source with the dominant wind direction all the year round in close range.
4. Residential geomantic omen pays the most attention to sunny air, so choosing a house should not only have fresh air, but also have plenty of sunshine. If it is a house with insufficient sunshine, there are often too many cloudy days, which will lead to restlessness in the house and make people feel depressed. It is really not suitable for living.
From a scientific point of view, sunlight contains ultraviolet rays, which has the function of sterilization. There are all kinds of bacteria in every corner of the earth. If people's body resistance is weak, germs will have an opportunity. Sunlight is very beneficial to people's health. As long as the sun is gone, its ultraviolet rays will remove a certain number of germs. Therefore, it is best to choose some buildings with more doors and windows when buying a house, and the sunshine will be more abundant. On the contrary, if the house is overcast and cloudy, it will affect people's health and is not suitable for buying and living.
