As the old folk saying goes: "If someone dies, it will be bad luck for whoever he touches."
The moment a person dies, he will exhale a breath of turbid air, which is called "disaster air" - some people also call it "death disaster" or "evil air". This breath is wrapped in the last obsession, fear, unwillingness and secrets of life. People who are exposed to bad luck may fall ill or die misfortunely. According to folklore, cats and dogs jumping over corpses and roosters crowing in the mourning hall are all bad omens for "explosion" of disaster energy.
Before the funeral, Mr. Yin and Yang must calculate the time and direction of the "disaster" so that family members can avoid it in advance. This is a rule passed down from older generations, and many rural areas still pay attention to this.
But there is a kind of person who doesn't hide.
They are specifically designed to take this kind of trouble.
