However, due to the long time, there will always be some damage to the tomb. For example, when choosing a site, the low-lying or empty ground will cause the grave to sink. This is a great disrespect for ancestors, and it also destroys the original feng shui pattern, which is not good for future generations. Especially when sweeping graves, it is unlucky to find small mounds pushed by insects or other animals. The ancients thought that this would lead to the descendants blessed by the ancestors in the early stage, because of the change of geomantic omen.
We know that the feng shui of the tomb is a whole. Once something goes wrong, the wealth of the mausoleum will be revealed. Ethically, future generations must ensure that their ancestors rest in peace, but these small mounds come from the earth arches in the graves. First, these animals disturb the peace of our ancestors, leaving them in heaven, thinking that future generations will be angry if they are unfilial; Second, the whole tomb destroyed the original intention of the previous eight-character site selection. Good feng shui in cemetery can bring good luck to future generations, while "bad feng shui" will be counterproductive. These small mounds are desecrating Feng Shui, thus affecting the wealth of future generations.
In fact, ancient people paid special attention to the feng shui of tombs, which is also the reason why the ancient feng shui theory prevailed and can be passed down to this day. All previous dynasties paid special attention to the burial place behind them. In order to prevent others from destroying their feng shui, many institutions are often set in tombs, which is also to protect themselves from being disturbed by outsiders after death, thus benefiting future generations. Although modern people don't pay as much attention as ancient people, if someone destroys the ancestral graves, it is estimated that they will not get away easily.
In short, the rural saying that "everything grows on the mound in front of the grave, and it is rich first and then poor" means that the integrity of the grave is broken, thus destroying the ancestors' blessings to future generations. It sounds superstitious, but it also involves ethics. Otherwise, the tradition of sweeping graves in Tomb-Sweeping Day is meaningless, so it still makes sense.
