The courtyard wall can block air from all directions, and the purpose of opening the courtyard door is to open the courtyard door in an auspicious direction, just to collect auspicious air and keep bad air out of the courtyard wall.
Now you say this courtyard wall has been torn down. I don't know what the specific situation is. If the peeling area is larger, so that the outside air can be accommodated from this position, it depends on whether this position is auspicious or fierce.
