It was called "tuyere" in ancient times. Refers to the close proximity of two buildings, resulting in a rather narrow gap between them. Seen from a distance, the building seemed to be broken by a sharp axe falling from the sky and split in two. Evil spirits, such as "wind knives", cut head-on and hurt people invisibly. And the higher the two buildings, the closer the distance, the greater the damage. Cutting the sky is characterized by fast wind speed, strong air impact and the power of "there is no smoke without fire".
And the wind level 3 or 4 can be increased to 8 or 9 strong winds. Yang Zhai meets this evil wind, which is called "heaven beheading", while Yin Zhai violates this evil wind, which is called "concave wind", all of which are evil. And the closer the devil is to you, the worse the influence will be.
But according to this photo, it is obvious that the sky has not been smashed, so you can rest assured!
