Why do some people say that graves have souls and others say that graves have no souls?

There should be no soul in the grave, and the soul will be reborn, but the grave will leave an aura, and the aura of the ancestors will have an impact on future generations. Therefore, in Feng Shui, there is a special Yin House Feng Shui, which talks about the influence of the deceased ancestors on future generations. The soul will be reincarnated.
