Is it a change of geomantic omen in different places?

Judging from what you described, it should be a matter of feng shui. According to common sense, if future generations live in peace and there are no more vicious problems, even if the geomantic omen is no better, you should also consider the problem of moving graves in your family. Your question is simple. Find a local Feng Shui and tell him your application. He will find a way to solve it, or move the grave. Just find a purpose nearby, but it wastes a lot of money.
