Many times, the "virtual shapes" formed by "tangible" objects often cause many unexpected diseases and disasters.
In particular, the "virtual shape" formed by the environment outside the house cannot be resolved simply by placing objects randomly.
For example: a narrow gap formed between two high-rise buildings side by side is like being cut in half by a knife in mid-air, which is also called "Heavenly Cutting Evil".
Generally speaking in Feng Shui, the most commonly used methods to ward off evil are: covering, blocking, controlling, transforming and avoiding.
Different situations require wise selection of appropriate handling methods, and when facing this kind of "virtual" evil, the most practical way to deal with it is to avoid it.
