How do traditional customs in China use salt to exorcise evil spirits?

Sprinkling salt to exorcise evil spirits is a folk custom in China. People think that sprinkling salt can exorcise evil spirits and bring good luck. This custom originated from the ancient superstition that salt can ward off evil spirits. Here are some possible explanations for spreading salt to exorcise evil spirits:

Exorcise: In ancient times, people thought that evil forces such as evil spirits, ghosts and evil thoughts would bring misfortune and disadvantage to people, while salt has the power of purification and can protect people from evil forces.

Eliminate disasters and avoid disasters: salt is regarded as a mascot, and sprinkling salt is considered to dispel disasters and unfavorable occasions and bring peace and good luck to people.

Auspicious implication: In China culture, salt has an auspicious symbol, because the pronunciation of "salt" is similar to that of "delay" and it is associated with blessings such as "long life".

Beware of suspicion: Sprinkling salt can also be used to "crack" some superstitions in harsh environment or traditional customs. For example, sprinkling salt on the dining table can dissolve the suspicion and jealousy among guests and ensure a harmonious and friendly atmosphere.

It should be noted that sprinkling salt to exorcise evil spirits is a custom and superstition, which has no scientific basis and cannot be used as a code of conduct in modern life.
