The installed upper hanger module looks something like this, credit from Baidu Tieba and QQ. We can see that there has been two unfinished elevator modules being installed to the ship's starboard side. No sign yet for the third elevator hole on the left portside side of the ship because if there is a third one it is definitely going to be more backward to the rear.
