According to feng shui, there can't be windows and doors behind the seat. Do I count? Behind the right is a door, and behind it is a ventilation window, which doesn't let the light in.

Feng Shui, in short, is an environmental science. There should be a backrest behind the seat, not a door or window. Actually, it's easy to explain There is nothing behind you, except that you can't see anything behind you. There are doors and windows in the back, and its safety is definitely not as good as a solid wall. Privacy is easy to leak, so you have the conditions to let others walk behind you. If someone stands behind you unconsciously, you will be surprised when you suddenly find it. Secondly, the sound insulation effect of doors and windows will be worse, and your every move may be seen and heard. This will definitely have an impact on you.
