What is the reason for the continuous death of a family?

Many times, the reason for the death of consecutive family members is heavy mourning.

If only one person leaves in 1 or 2 years, it is because there are many men (8 out of 10 are men), which is the geomantic reason for losing men continuously. If there are both men and women, the time of death is one person a year, or the family loses several people in a row a year, it is a heavy loss.
