How did Yin Qi's face sink? Explain from both feng shui and science?

From a scientific point of view, the complexion will look pale, even if the skin is black, there will be pallor, especially after sweating, which is very obvious and generally a little kidney deficiency. From the perspective of geomantic omen, there is too much moisture in the place where you live, that is, the gathering of Yin Qi, the lack of warm Yang Qi, poor ventilation and people's easy fear of cold, all of which are combined with the factors of ancestral graves. In my opinion, in this case, we should first consider whether the place where the ancestral graves are buried is angry. If we are not angry, it will affect our health. Finally, the low terrain at home also matters.
