Why can't the house be built in the valley basin?

The valley basin is low-lying and easy to avoid evil spirits. In modern society, valley basins are more susceptible to pollution. Due to the existence of mountain breeze and temperature difference, the valley is vulnerable to air pollution. During the day, the hillside is warm by the sun, and the temperature is higher than that of the valley, resulting in inversion, and the valley wind blows upward from the valley; At night, the hillside dissipates heat quickly, the temperature drops to be lower than that of the valley, and cold air goes down the mountain, forming a mountain wind blowing from the hillside to the valley. It's like the ebb and flow of the tide, with a pause in the middle. During the intermission between mountain breeze and valley breeze, it is the most unfavorable to the diffusion of pollutants, and a large number of pollutants stay in the valley, causing air pollution. Therefore, it is not suitable to build houses in the valley, but on the hillside, preferably on the sunny hillside.

Don't build the house into a basin. If the whole building foundation of a residential area is lower than the surrounding terrain, it makes people feel like living in a basin. The terrain is not well ventilated, daylighting and drainage, and they feel uncomfortable when they go home every day. Moreover, from the perspective of geomantic omen, some heavy polluted air often accumulates in the basin area, which has obvious damage to the health of residents, so we must pay attention to it when buying a house.

? First, the big pattern?

Qinglong white tiger sand, the ideal building has mountains around it, but these mountains are shorter and smaller than the mountains, otherwise it is not an ideal feng shui. On the other hand, there are no mountains on the left and right sides of the building, which is called the lack of "Qinglong Sand" and "White Tiger Sand" in geomantic omen. But there are buildings on both sides, which is auspicious. The dragon is strong and the tiger is weak. In feng shui, the dragon is strong and the tiger is weak. The dragon is the dragon, pointing to the left, also known as the left auxiliary side and the left sand hand, referred to as the left hand. The tiger is the white tiger, which refers to the right side, also known as the right hand and the right hand sand hand, referred to as the right hand.

There are four kinds: 1, where the dragon is the dragon and the tiger is the tiger-the hill or building on the left side of the building is higher and the hill or building on the right side is lower. 2. Long tiger is short-the hill or building on the left side of the building is longer and wider, and the hill or building on the right side is shorter and narrower. 3. The dragon is close and the tiger is far away-the hill or building on the left side of the building is close to itself, and the hill or building on the right side is far away from itself. 4. The prosperity of the dragon and the decline of the tiger-there are many hills or buildings on the left side of the building and few hills or buildings on the right side.
