Feng Shui: Sleeping in front of a tiger's mouth all day is an inescapable fate.
Science: When you sleep, your body's resistance is the weakest. At this time, the cool wind coming in from the window can easily make people sick.
Avoid freedom behind the bed, there is a mirror in front of the bed.
There should be something behind the bed. If the bed is empty, it is called "the sun never sets." Leaving blank means that there is no back hill and no backer. Explain that the career is unstable. If there is no support at both ends of the bed, it is called "Shen" bed in geomantic omen. A pillar behind the bed means that you can only rely on half, and you are still helpless.
The mirror shouldn't face the bed. The role of mirror in geomantic omen is mainly used to reflect evil spirits, fight against evil spirits that come straight at you and avoid being destroyed by evil spirits.
Comments: If the bed is empty, the stability is poor and there is psychological insecurity, but it has nothing to do with the stability of the occupation. The mirror is facing the bed, and there will be a shadow when you get up at night. If you are not awake, you will feel unsafe after seeing the shadow. If you do this for a long time, it will affect your sleep and health, but the mirror has nothing to do with the murderer.
