In rural areas, affected by topography, many places are pitted, so the water level below the ground is different. Farmers generally don't build houses at high water levels. According to the geomantic theory, if the water level is too high, the house will be too cloudy. The scientific explanation is that the house is easy to get wet and the moisture attacks people.
The second point: Yixing houses are not built on steep slopes.
In mountainous rural areas, there are some steep slopes and sand beams. Some people think that it is highly permeable and well drained, which is suitable for building houses. Actually, I don't think so. Where the slope is steep, the dragon is fierce and unstable. In fact, the slope is steep, and the foundation rock and soil may have potential landslides, which are unstable and not suitable for construction.
The third point: uneven subsoil and uneven gas are not suitable for buildings.
In rural areas, some plains may be deposited by river beaches for a short time. This kind of foundation is likely to have uneven soil at the bottom, some hard and some soft, but not as good as all soft soil. After the completion of the foundation, the uneven stress will easily lead to the leakage of ground gas, which is not conducive to family wealth.
The fourth point: the gas in gravel foundation is easy to leak and insufficient.
In rural areas, there are still some places where the soil is soft and mixed with sand and gravel, so the soil is wet, and there is not enough gas in this foundation, so it is difficult to gather wealth after geomantic omen talks about the house. Therefore, it is best to clean up the surface gravel first, exposing a solid bottom, and then start building a house.
