The grave Fengsui is a systematic life science, explained by the life energy of Yin-yang and Its five elements. The life energy of Yin-yang and its five elements, though Invisible and thus difficult to apply, Is easily conceived of as the magnetic force. When the life energy of the grave Fengsui is not understood as ambiguous moving force but as magnetic force, It is possible to open up a new field of Fengsui life culture.
