What is the effect of planting mango trees in front of Feng Shui ancestral graves?

Planting trees in front of the grave depends on the distance and orientation, and the distance should not be too close, otherwise the roots will destroy the golden basin and the crown will block the sunshine in front of the grave. This is all terrible. As for some people who say that only pine and cypress trees can be planted in graves, I don't quite agree. It can only be said that there is some truth, because the crown of pine and cypress is not very big, and it is not easy to grow into a tree that can block the sun from the grave, that's all. Therefore, there is no harm in planting only some small shrubs or flowers in front of the grave.
