Why is there a backing at the bedside

There should be a backing behind the bed. If there is an empty behind the bed, it is called "the sun does not reach the stars". A blank space means that there is no backing or backing on the mountain. Indicates that the career is unstable. If there is no support at both ends of the bed, Feng Shui is called a "Shen" bed. Behind the bed is a pillar, which means that it can only be relied on halfway, and it is still not reliable. If you are empty behind the bed, your stability will be poor and you will feel insecure, but it has nothing to do with the stability of your career.
