The Three Zones Method (Samjeong) divides the face vertically into the Upper (hairline to brows), Middle (brows to nose tip), and Lower (nose tip to chin) zones, representing early life (15-30), mid-life (31-50), and later life (51+). The Upper zone reflects academic focus and parental luck. The Middle zone, led by the nose and cheekbones, governs mid-life career success and wealth. The Lower zone, highlighted by the mouth and jaw, indicates retirement comfort and junior luck. Balanced ratios (approx. 33.3% each) denote a smoother, well-supported life path, while severe asymmetry suggests times when caution or extra effort is needed.
