If there is a second doorman, it is best to change the bathroom door of the national highway into the master bedroom and hide your aisle wall in the room with a closet. Make a wall painting and draw it on the sky or grassland, as long as it looks vast. You can draw some dried flowers below, separate the crural lines with glass strips, fill them with sand, and insert dried flowers, so that there will be flowers. As soon as you enter the door, you can see that the background of the corridor looks vast and not so depressing.
