Avoid sitting with your back to the door. If the desk is placed near the door, people sit with their backs to the door, which is the basic point to avoid when putting the desk first. The door is the only place where people enter, the air inlet of the office, and the place where they can be angry, including anger and suffocation. If a person sits with his back to the door, there is no support behind the seat, and there are people coming and going behind him. For a long time, the office workers sitting here are always in a subconscious state of tension. Sometimes it seems that someone is peeking, which will lead to confusion and dryness, and even meet little people and things at work. This situation is called "cold wind blowing back" in geomantic omen.
In ancient times, the screen was erected at the back, so it was better to adjust the work.
