Steps
Total steps: 21 steps
(21 - 1) % 4 + 1 = 1 -> Stage Life (Sinh) (Auspicious)
162mm/step -> Riser height of 162mm is too shallow. Consider recalibrating to 21 steps.
Quick Answer & Understanding Your Result
In architectural Feng Shui, staircases channel vital energy (Qi) across residential stories. Step counts are determined by the Life, Aging, Illness, Death cycle:
The 4 Cosmic Step Stages
- 1Life Stage (4n + 1): Supreme vitality, blossoming affluence, peaceful family harmony. Common auspicious counts: 13, 17, 21, 25, 29 steps.
- 2Aging Stage (4n + 2): Long healthy life, stability, and enduring ancestral blessings (14, 18, 22, 26 steps).
- 3Illness Stage (4n + 3): Portends vulnerability to health strain and asset dispersion.
- 4Death Stage (4n): Strictly taboo; symbolizes stagnation and depletion of domestic vitality.
