Is the staircase of the double-hall villa in the feng shui center of the back hall all right?

Is the staircase of a double-hall villa feng shui in the center of the back hall? -Stairs are practical, convenient, comfortable, safe and easy to manage in any position, and feng shui is well decided. Feng Shui has no puzzling meaning. Practicality, convenience, comfort, safety and easy management are the essence of Feng Shui. Excellent feng shui must achieve these basic essentials. Not practical, inconvenient, uncomfortable, unsafe and difficult to manage. It is empty, evil and harmful. Another problem with the location of stairs is that stairs should be hidden, not too exposed, to avoid some emergencies, and its essence is safety and easy management. Stairs are at the back of the hall, which fully meets these conditions and should also fully meet these requirements of Feng Shui.
