It's really bad for the bed to face the balcony door, which is called wearing a hall evil spirit; This is a traditional geomantic omen theory, and it is also a custom. It is believed that the bed should not be placed vertically against the door, let alone sleep with its head facing the door on this bed, because only when the dead are put on hold in the mourning hall can the head face the door. Treating the living with behavior similar to treating the dead will bring disaster to the living. From the physical and psychological point of view, the bed facing the door will give people a feeling of insecurity, and they always feel that someone will come in, so they will not sleep steadily, which will affect their rest and will not be good for people's physical health over time. The best thing is to move the bed and pull over. If you really can't change the position of the bed, you should put a screen or hang a curtain between the door and the bed, which has the same effect. Its advantages are: 1) from the perspective of geomantic omen, it can eliminate disasters and block evil spirits; 2 psychologically speaking, increase the sense of security; From the perspective of basic human rights, it is to protect personal privacy.
