Is the door of the house facing the intersection of the canyon ahead?

The door is facing the intersection of the canyon or the mountain, which was called mandibular evil spirit in early geomantic omen. Because of the unstable airflow energy and inconsistent geomantic omen on the road, it is necessary to set up fences or shelters outside the door and place special geomantic omen ornaments at the threshold to block evil spirits for a long time, so as to improve parents' personal luck and fortune.
