Is it credible for Wutai Mountain Buddhism to look at ancestral graves?

Buddhism does not advocate showing people Feng Shui.

You can go to Taoism to find someone to see Feng Shui.

But: one life, two luck, three goodness and four feng shui, if the family is kind, it can change the feng shui of the environment.

This is one of the reasons why Buddhists only teach people to do good deeds and do good deeds without showing people Feng Shui.
