What if there is a pig shed in front of the grave?

There must be a pig farm in front of the cemetery that affects Feng Shui, but the law does not support Feng Shui. The land use right belongs to others and has no right to interfere. You can only do what you want.

On the issue of tomb geomantic omen: Yes, one of the issues involved is tomb geomantic omen! In the final analysis, it is still a question of "heart orientation". Who he admires, what kind of terrain it is, and why he uses this land instead of other terrain can fully reflect the success of his "mind" in using things and educating future generations! Therefore, Feng Shui is not "innate", but "acquired". In other words, whoever makes use of the so-called land of geomantic omen will prosper forever, and the answer is absolutely no. But as long as people are in power, even if they use physical geography and geomantic omen almost, they can move towards glory. The key is "heart orientation", which determines success or failure. This is true at all times and in all countries. The geomantic omen of the tomb can not determine the success or failure of future generations, but it can test some characteristics of their success or failure.
