Hotel stairs

Basically, outdoor stairs are added. If you don't do outdoor stairs, it's better to do the stairs opposite to A. Considering that in case of fire, evacuees can evacuate from two different directions, and the distance between the two stairs is too close (the specification seems to say that the minimum distance between the two evacuation stairs should not be less than 5m), which will cause people to be crowded when evacuating, and it will be bad if they are trampled!
