What is the explanation for closed-door burial?

Burial with closed door is the most poisonous burial method among the people.

"Closed door burial" is the most poisonous burial method among the people. It refers to placing the coffin at the door of the living room, sealing the door, and turning the house into a cemetery. In the Feng Shui array layout, if this method is adopted, the family will not be able to stand up for three generations, even if they are slightly related by blood, they will not be able to escape. Maybe this statement is superstitious, but closed-door burials do look scary. After death, people should originally return to their ashes, but they are placed in the houses of living people and use the houses of living people as burial sites. I believe no one can bear it.

From a scientific point of view, the coffin camphor cannot completely block the odor of the corpse. It will take only a few months for the stench to become so strong that the burial will be closed and buried. It can be said that it is a rare occurrence in a century. If it were not for deep hatred, it would be very difficult. Hard to see.
