What's the point of throwing dog blood at someone else's door?

First of all, it's wrong to throw dog blood at someone else's door. Its meaning is mostly used to exorcise evil spirits, but it has no scientific basis.

As a magic weapon to ward off evil spirits, dog blood has been recorded in history books. Qin Shihuang's four lessons of killing dogs and preventing fierceness are one example. Since then, killing dogs and smearing blood on the door has always been one of the basic ways for the people to eliminate ominous or resist evil. Folk beliefs also believe that dog blood and chicken head are the easiest ways to solve evil spirits, especially chicken head and black dog blood.

If you encounter a "demon" who uses magic, such as cutting paper into horses and scattering beans on soldiers, you can also splash dog blood to break its magic. In folklore, chicken blood and dog blood are also commonly used together to hate evil spirits. However, there is no scientific basis for this statement, so we must put an end to bad behaviors such as sprinkling dog blood and killing animals.

Sprinkling dog blood means driving away evil spirits and bad luck;

But this kind of statement often comes from hearsay, has no scientific basis, and is often useless when it hurts animal life. Therefore, in life, after conflicts with neighbors are discovered, it is still the first choice to solve them through communication or even through relevant legal channels.
