1. The strata should be oriented in the north-south direction, accompanied by geomagnetic attraction. Sleeping with your head facing south or north is good for your health, because in the blood circulation system of human body, the direction of aorta and great vein is the same as that of head and feet. When the human body is in the north-south sleeping direction, the direction of aorta and great vein, the direction of human sleeping direction and the direction of magnetic field lines in the north and south of the earth are the same, so people are the easiest to fall asleep and have the highest sleep quality, so the north-south sleeping direction has certain disease prevention and health care functions.
Behind the bed is not the toilet.
The bedside should be against the wall, not by the window. If the bed is not against the wall, there must be a headboard at the bedside. Opening the window at the head of the bed is a taboo of geomantic omen, so you must remember it.
4. Suppose you are lucky, but your bedside faces east, and the east is wood, which leads to Jin Kemu, which is not good either.
Take the bedside as the standard. The right side of your bed can't be against the wall. Try not to get close to the bedside window.
