Xiaoming and Xiaoying are racing to climb stairs in a high-rise building. They start from the ground floor (first floor) and return to the ground after reaching the 28th floor. When Xiaoming reaches the 4th floor, Xiaoying has just reached the 3rd floor. If they maintain a constant speed, on which floor will Xiaoming meet Xiaoying while he is descending after reaching the 28th floor? (Note: The stairs between the first and second floors are considered part of the first floor, and so on.)
