First of all, we need to know the distance and orientation of the new grave from the ancestral grave, as well as the size and shape of the new grave, so as to judge whether it will have an impact on the old grave. Secondly, you need to consider the source and background of the new grave. If the new grave comes from other families or beliefs, it may have a negative impact on your family.
If you think that the new grave has had a negative impact on your family, you can consider taking some measures to alleviate the impact. For example, you can add some barriers around the ancestral graves, or adjust the orientation of the ancestral graves. If the situation is serious, you can also ask some professional feng shui masters to help solve it.
In a word, it is very important to respect and protect ancestral graves. If the ancestral graves are affected, measures should be taken in time to solve the problem. At the same time, we should also pay attention to getting along with people around us and avoid affecting the family fortune because of some small things.
