The "evil spirit" in Feng Shui comes from the aura. When the aura remains balanced, good and bad luck are relatively stable; when the air flow changes, the home fortune will be affected to varying degrees. There are two kinds of power that can affect changes in the aura: one is the "star" power, such as the good and bad luck of flying stars; the other is the "dark" power, such as Feng Shui instruments, weak energy and evil energy on the body, etc.
Ancient Feng Shui divided "qi" into "anger" and "evil energy". Anything that is beneficial to the physical and mental health of the residents is called "qi", and anything that has adverse effects is called "evil energy". Evil spirits are mainly divided into seven categories: shape evil, taste evil, light evil, sound evil, rational evil, color evil, and magnetic evil.
If you encounter evil spirits, Feng Shui advocates using methods such as covering, blocking, transforming, fighting, and avoiding to deal with them.
Xingsha is a visible and traceable evil. Mainly refers to the unreasonable natural landscape or artificial buildings (including both shape and orientation) distributed around the villa. Shape refers to tangible objects that can be directly felt by people's five senses; Sha refers to internal and external environmental factors that are harmful to people's physical and mental health.
