Hello! In feng shui, this kind of thing is called there are trees on the grave, including all the trees. The better the tree grows, the implication is that it has been blessed by its ancestors. You can't cut them down at will, even if they are green plants such as flowers and plants, because they are used to block graves. Tell you a real example, my neighbors are all rural, and her cemetery is a sunny plot near their fields. This is the tomb of generations. There were many lush weeds on that grave, so she cleared all the weeds on it. She thought of guarding the grave, and on the third day she had an accident and fell down. She still hasn't recovered. Not only that, her son was paralyzed because the grave where she mowed the grass was moved from nearby to the field. Since she moved to the ancestral grave, her family has been unlucky and has been incomplete. Later, I found a knowledgeable person who said that the ancestral graves really shouldn't be moved casually, because I wanted to build a house, so I just found a person who was not good at it and moved out. Now there is a lot of lush grass on the grave where I moved out, and they cut it off at will. On the third day, the mower fell down. Up to now, my thighs are hard and it is not convenient to walk.
There is a cypress tree in your grave. Very good! This position is auspicious, and it is a blessing that future generations are developed and trees grow taller. Don't cut it down. These are all my experiences. Good luck!
