Can the ancestors' trees be pruned?

Of course. In fact, from the perspective of geomantic omen, it is better to trim the trees above the cemetery.

We often see some mass graves mentioned in TV dramas, which are eerie. Why do we feel gloomy and horrible? It is because there are too many trees in the cemetery that have not been pruned. In fact, there is a concept of Feng Shui called "Bureau". For a long time, the trees are in one place, and the wind gathers in the gas storage. It is appropriate to break them. The five elements of trees belong to wood, so it is logical to break them with "gold". Therefore, for the sake of future generations, the cemetery also needs to be maintained frequently, but pruning trees is not arbitrary, and there are still some precautions.

If there are big trees on your grave, it only means that you haven't visited the grave for many years. Because trees grow slowly, if you go to the grave every year and meet some young trees and grasses that have just grown, it will be easier to clean them directly, and it will be very troublesome to prune them without waiting for them to grow into towering trees. Of course, if it really grows into a big tree, you must try to cut it down, but if you cut it down, it also means moving the cemetery, so you must choose a better time to prune it, such as Tomb-Sweeping Day and Halloween.
