Four-Pillar Palace Diagnostics: 巳 (Sì) & 酉 (Yǒu)
When evaluating Snake (巳) and Rooster (酉) in authentic Four-Pillar synastry (合婚), classical practitioners inspect which natal palace hosts the 巳–酉 vector (Three Harmony Trine (三合) · 巳酉丑三合金局). 巳 governs the 4th Lunar Month (Start of Summer · 立夏) command (09:00 – 10:59, South-Southeast (150°), Six-Harmony ally Monkey 申), whereas 酉 anchors the 8th Lunar Month (Autumnal Equinox · 秋分) command (17:00 – 18:59 (Sunset), Due West (270°), Six-Harmony ally Dragon 辰).
Across the 12-branch ecliptic wheel, 巳 (#6) and 酉 (#10) sit 4 steps apart, creating a 91% baseline resonance between Yin Fire (Si Snake (巳蛇) — The Alchemical Strategist & Birthplace of Metal) and Yin Metal (You Rooster (酉鸡) — The Equinox Artisan & Crystalline Critic). Introducing Metal remedies bridges the South-Southeast (150°) and Due West (270°) sectors while stabilizing their 2026 Bing-Wu trajectories (Snake: Si–Wu–Wei Southern Fire Convergence (巳午未会火); Rooster: Hong Luan (红鸾) + Tai Yin Noblewoman Star).
