2. Don't walk west in bed. People regard the west as a "paradise", which they yearn for after death. Even from the perspective of modern science, it is not appropriate. The sun sets in the west, the earth rotates from east to west, and the head sleeps in the west. Over time, it is easy to cause blood to rush to the ear. So don't walk west in bed.
3. The bed should be ventilated and clean. In order to prevent wet pathogen infection and hinder health. Don't place sundries under the bed, especially avoid iron and glass. So don't put the bed near the ground.
4, the bed is best not to face the door. People lying at the first viewing gate of the bed must be clear at a glance, otherwise they will be easily disturbed and frightened, which will affect their emotional health. The bed should not be exposed to strong light. If it is too dazzling, it will easily hurt the liver, so the bed should avoid strong light.
