Why is Yin Qishan heavy?

Because the mountains in the northern hemisphere are sunny in the south and cloudy in the north, Yin Qi in the north is usually heavier, but in mountainous areas with many trees and water, Yin Qi is heavier and the humidity is heavier. First, if the building is located at the foot of the mountain and the hillside is facing the building, there will be a heavy sense of suffocation when going down the slope. The steeper the hillside, the heavier the sense of suffocation. Living in such a house, living in such a house, the residents' fortune will become more and more depressed because of the influence of Shaqi.
