Quick Answer & Understanding Your Result
Can Chi compatibility evaluates relationship harmony by comparing Heavenly Stem interactions (Hop/Pha), Earthly Branch relationships (Tam Hop/Luc Hop vs Tu Hanh Xung), and Five Element dynamics (Tuong Sinh/Tuong Khac).
The 3 Core Pillars of Eastern Compatibility
- Heavenly Stems (Can): 5 Harmonious Pairs (Giap-Ky, At-Canh, Binh-Tan, Dinh-Nham, Mau-Quy) vs 4 Conflict Pairs.
- Earthly Branches (Chi): 4 Triad Harmonies (Tam Hop) and 6 Intimate Pairs (Luc Hop) vs 180° Direct Conflicts.
- Five Elements (Ngu Hanh): Generating Cycles (Thuy sinh Moc, Moc sinh Hoa) vs Overcoming Cycles.
Scoring Breakdown
- 85–100 Points: Excellent Harmony (Dai Cat) — natural mutual support and prosperity.
- 70–84 Points: Favorable Synergy (Binh Hoa) — strong bond with easily resolvable differences.
- Under 50 Points: High Friction (Khac Ky) — requires conscious understanding and Feng Shui balance remedies.
