Why shouldn't houses be built in the valley basin

The valley basins are low in terrain and easy to accumulate dirt. In modern society, valley basins are more susceptible to pollution. Valleys are vulnerable to air pollution due to valley winds and temperature differences. During the day, the hillside is warmed by sunlight, and the temperature is higher than that of the valley to form a temperature inversion. The valley wind blows upward from the valley. At night, the hillside heats up quickly, and the temperature drops to lower than the valley. The cold air descends, forming a mountain breeze from the hillside. The valley blows. This is like the rise and fall of the tide. There is an intermittent period in between. The intermittent time between the mountain wind and the valley wind is the most unfavorable for the diffusion of pollutants. A large number of pollutants stay in the valley and cause air pollution. Therefore, it is not advisable to build a house in a valley, but on a hillside, and preferably a sunny hillside.

Don't build houses into a "basin" pattern. If the foundation of the entire building in a residential area is lower than the surrounding terrain, it makes people feel like living in the basin. This kind of terrain is not good for ventilation, lighting, and drainage, and it feels uncomfortable to go home every day. In addition, from the perspective of Feng Shui, the basin area often accumulates some dense turbid air, which has obvious damage to the health of the residents, so you must pay attention when buying a house.
