The house is built on a hillside, with poor soil and water conservation and soft foundation, which is very fierce.
Houses should not be built on the edge of cliffs.
The house is built on a cliff on a mountain or by the sea. No matter whether the foundation is solid or not, it is easy to produce "insecurity" in the subconscious, and the mental state is unstable, which is easy to cause anxiety and mental weakness. Although the terrain is beautiful, it is dangerous, so temples, monasteries or tourist hotels should be built.
Houses should not be built at the outlet of rivers.
The house is built on the alluvial fan of the dry river; Big killer. Because the geological formation age and causes of this kind of place are not strong enough, it is not suitable for buildings. Moreover, the outlet of the river valley is often a "scattered" place, and the atmosphere is easy to vent rather than condense, which is harmful for long-term detention.
Houses should not be built in dangerous places.
There are chemical plants and warehouses for storing dangerous goods near home, and the doors face temples, courts or police stations, prisons, hospitals, funeral homes and so on. Affected by bad "qi", it should be regarded as unlucky. Because the above-mentioned places are frequented by criminals, sick or unlucky people except their own staff, it is really bad to face the doors of these places.
