Two people died less than two years after Feng Shui was elected. Are there any rules for future security?

Can't you be more specific? A master is a human being, not a god. I can't be sure whether your present situation is related to Feng Shui, because you have given too few conditions. You should at least explain the following points:

The two people who died were male or female, age, cause of death, that is, symptoms, and were at home for three to six months before they died.

Is there any change, or is there anything related to the grave, and whether you live in the city or the countryside and how big the area is? . .
