The bed has no head. How about leaning against the wall directly?

In geomantic omen, the bed in the bedroom must rely on a solid wall. If the bedside is not against the wall, the unstable gas field will seriously affect the quality of sleep and easily lead to colds, anxiety and helplessness. In the long run, it will consume Yuan Shen and lead to physical and mental collapse. In fact, it is very wrong for some families to keep their beds away from the wall in order to avoid the evil spirits. The solution is to move the bedside near the wall. You can also put a screen cabinet at the bedside without leaning against the wall. In fact, superstition says that the bedside is near the western wall, and the old man in the main house is good. In fact, the earth rotates from west to east. The best sleep is with your head facing east and your head facing north, which is easy to have nightmares. It's hard to sleep with your head facing south. So I suggest you lean against a solid wall no matter where the head of a bed faces, because the head of a bed is close to the solid wall.
