However, there is indeed a doorway at the bedside that does not face west, and that is the direction of the earth's rotation. If the head of the bed faces west, we sleep in the opposite direction of the earth's rotation. The physical strength added when sleeping is definitely not as good as that in other directions. Because we have to take out some physical strength to offset the functional loss caused by relative exercise.
In the long run, this is not good, and what dark circles, bad temper, nightmares and so on will follow. The most terrible thing is that children's height will be affected if they sleep like this. Only when you sleep well can you grow taller. And maybe intellectual development will also be affected, and taller people will pay attention.
But it doesn't mean that everyone can't face the west. If you are slow and inefficient, you might as well try sleeping like this, which will improve, but it will never last long. If you have nothing to do, you have no fighting spirit, but you really want to have it.
The statement that the bedside can't face west is all the words of the old man. Because China people think that people go to the west after death, to the paradise of the west, and to drive cranes to the west. When you sleep, your eyes are closed, you are unconscious, and you lie down. It's almost like a state of death, with your head facing west.

The following excerpt is taken from Talking to Maids: "The biggest difference between this room and other palaces is that the bedside where the old lady sleeps is a big transparent glass against the fan in the north of the dressing room. The old lady sleeps with her head facing west. She leans on the kang and lifts the curtain, so she can gain insight into everything outside. "
