The stairs are in the middle of the room.

In the middle of the house, it is a very important position. I regard this position as a person's heart. It is best to be open and the ground should be flat. Nothing can be put in this place, or it will be broken. [Don't say how bad it is here] If your stairs are eccentric, there is not much problem, but you should avoid seeing the stairs as soon as you enter the door. If you can't see the stairs, there won't be a big problem.
