What if the ancestral grave is not feng shui?

Well, such a strange question. The ancestral graves are low-lying and prone to water accumulation, which will have an impact on the deceased. But I don't know much about strangers. But according to the water book, low terrain is not necessarily bad, because many shapes need low terrain. Personally, if a fortune teller is really good, he should go to him and bring something to others. If it's cheating money, I personally think it's better to give incense to the ancestral graves and comfort the world.
