What should be paid attention to when the elderly are buried together?

Hello! It seems that you are a filial grandson, but you only stated the anniversary of your mother's death, not your birthday. In addition, it does not explain the sitting direction of the buried geomantic treasure. Concise: If the lives of two ancestors collide, don't be buried together, and don't collide with their ancestors on the selected day. If you want the mountain people and ancestors to match the nobles of Ma Delu in Tiandeyue, please ask the Feng Shui master to go to the treasure land to measure the mountain situation first, and then choose another day.
