I feel that this question is still difficult to answer, because after all, different situations will herald different results.
Generally speaking, I think this thing is still believed, so it doesn't exist, or it should be eliminated optimistically, especially when it comes to these things related to superstition. I think it should be analyzed objectively and rationally.
If there is a hole in the ancestral grave, I feel that this thing really has a great influence on people, or it will affect people's mood. There are actually two explanations for this kind of thing. Generally speaking, if you make a hole in the ancestral grave, it may have some bad effects. Because this is a disrespect for ancestors, and in the long run, it may also destroy Feng Shui, leading to worse fortune for future generations. These are all possible.
And these things, I think, have a certain basis in some cases, because after all, these things are interactive, and in most cases, they may have a greater impact, so I think in this case, they may have a long-term impact on us, but if we put aside these aspects for other analysis, we may get another result, but no matter what kind of result, there is actually a reasonable process in it.
In addition to this explanation, there is actually another explanation. Some people think that if there is a hole in the ancestral grave, it may have little impact on people, and it may have some positive effects, because we don't know what these animals are for, so I think its analysis is more important, depending on your mentality. If you have a better attitude, you may accept this thing. If you are not in a good mood, you may compare this thing. In this case, there are not many problems.
And for some specific things, we should also take a closer look at our own discrimination. Only by distinguishing these things clearly can we draw a scientific conclusion. If something goes wrong with these basic things, the problems in other aspects may be even bigger, so I think these things should be analyzed clearly before an appropriate conclusion can be drawn. Without these things, there may be bigger problems in other aspects, and these situations need attention, so no matter what kind of situation, we need to take it seriously and analyze it carefully to get an appropriate result.
