Feng shui does not mean wind and water, but a proper combination of elements needed by human production and life.
If there is no lighting in the house, then the yin is heavier, such as the residents at the bottom; If the light is too strong, it will form a light evil spirit and neurasthenia.
Therefore, the north and south are transparent and the yin and yang are balanced.
If you can't change it, you should pay more attention to window ventilation; The house mainly basks in the sun.
