If the door is open in an unlucky and fierce position and "angry", it is appropriate to set up a porch.
"Qi evil spirit" refers to the direction in which evil stars fly, because it is invisible and can be observed with naked eyes like "shape evil spirit" and can only be calculated by geomantic mathematics. But what is certain is that if the head of the household is Dongsi Life, and the gate is opened in the west, northwest, southwest or northeast, the gate collides with the head of the household, which is a "gas evil" gate for this family.
On the other hand, if the head of the household is Xi Siming, but the gate is opened in the east, south, north and southeast directions, and the gate collides with the head of the household, it is the "qi evil" gate of this family. For the people of the West Four Life, the fierce position in the north is the gate of evil spirits; It is advisable to set up a porch. The air outside the house originally flowed in from north to south, but now it is changed from west to east, and the west belongs to the auspicious side of the core historical site of life, which can turn everything into luck.
