It is a good thing in many cases! I have met some such situations, and my family is very developed! It was dug up in my own yard. The ancients paid more attention to feng shui, and most of them could do a good job in the cemetery and the location of the house! Buildings and single-family houses are naturally somewhat different.
Actually, it doesn't mean anything. There are many people in the building, and every feng shui is different. Digging into the grave won't make any difference. People with good feng shui are still very good, and people with bad feng shui are still not good!
