Legend has it that this burial method can't turn over three generations. Maybe this statement is a little superstitious, but buried behind closed doors looks really scary.
In the layout of Feng Shui array, if this method is adopted, three generations of the family will not be able to turn over, even if they are slightly related to each other, they will be born to die. Perhaps this statement is very convincing, but the door burial looks really scary.
People should return to dust after death, but they are placed in the houses of the living, and the houses of the living are used as cemeteries. I believe no one can stand it.
From a scientific point of view, the coffin can't completely block the smell of the body, and it will stink in a few months. It can be said that it is a once-in-a-century event to seal the door and bury the body. If there is no deep hatred, it is really hard to see.
Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
