Feng shui requires each floor of the duplex staircase:->; Can't the pedals be odd and even?

The odd number of stairs is auspicious, and even number is evil. The elegant semi-circular staircase in the living room is the best design, because it moves in a spiral shape and because it is angry and auspicious. Modern shopping malls often use ladder elevators to transport guests without going downstairs or less, which is also a feng shui symbol of making ends meet and rolling in financial resources.
