Whether the ancestral geomantic omen is safe or not, you can think about the family situation of your immediate blood relatives and what your ancestors were like at your father's age. If it's almost the same, it must be an ancestral grave, and the only way is to change the cemetery.
If cousins and other lineal blood relatives are doing well, only your family has such problems. Think about it. Have you ever moved or rebuilt your old house in the past five years?
If there is such a phenomenon, please ask the Feng Shui master to make an on-the-spot investigation to find the cause of the disaster.
In addition, many things can be reflected from numerology. You can also find a numerologist to analyze your horoscope.
Only by investigating the cause can we prescribe the right medicine. Only the right medicine can quickly change the unfavorable state.
