Grandfather's grave Feng Shui determines grandson or son.

Grandpa's grave is determined by Feng Shui, and the quality of Feng Shui has the greatest influence on his grandson, who will also be determined by his grave. Even if the graves of Grandson and Grandfather are separated from Wan Li, the quality of geomantic omen in the cemetery will have an impact on Grandson's fortune and destiny. However, as long as it is not buried in a barren land and in an ordinary place, Grandpa's grave will basically not affect the fortune of future generations. This answer is for reference only. Don't be blindly superstitious.
