How about not planting chestnut trees on the grave?

First of all, there are trees growing on the grave, indicating that the land is prosperous and the children and grandchildren are prosperous. This is a good cave. Second, whether trees are among auspicious tree can be divided into high and low, good and bad. Third, choose a good luck, tie a red line on the tree three days in advance, pray for the evil spirits on the tree to avoid it, and transplant it to other places three days later. Objectively speaking, if the tree grows too thick and the roots are developed, it is hard to say whether it will eventually affect the coffin. There are thorns all around. If you are not careful, you will hurt people. I don't know if the roots will affect the coffin. Generally speaking, when a tomb is cleared, it is necessary to clean the surface of the tomb. There is a saying that Screaming Trees grows well and grass grows well. Grass is usually planted on the grave when it rises.
