The importance of feng shui is nothing more than yin-based feng shui. It is unlucky to have a thorny tree on the grave. If these thorny trees cover the grave, they will be a huge demon.
In this case, the geomantic omen of ancestral graves is harmful to the eyes of grave owners and descendants. Trees cover graves with invisible eyes, and the most harmful to the eyes of future generations are thorny trees, such as jujube trees, locust trees and thorn trees.
The "thorns" of trees are the "nails" in the eyes, which will hurt the eyes. Therefore, the descendants of the feng shui tomb owner in this cemetery will have more eye diseases. If it is light, it will only hurt your eyes, and if it is serious, you will be blind.
If the root of the grave extends year after year, and the direction of extension happens to be the place with loose fertile soil, it may lead to the root of the grave. If so, future generations will not only have eye diseases, but also have great disasters.
The tree growing on the grave is big, and the roots will support the Jintan, and something will happen. Trees growing on graves are not good for Feng Shui and science. It means that the moisture in the grave is too heavy, so the trees grow luxuriantly. If not cleaned up in time, it will bring harm to future generations.
Some places say that planting trees on graves is a good thing, which shows that the atmosphere is strong. Some people still plant trees beside the grave, but if these trees are too close to the grave or too strong, they may string together the Jintan and cause damage.
To judge whether the tomb is damp, you can look at the stone tablet. If the tomb or tombstone is covered with moss, it means that the moisture is very heavy, and it may be that Jintan has been flooded into the mud. If the tombstone is dry and fresh, it means that Jintan is safe and can receive the earth's atmosphere.
