Four-Pillar Palace Diagnostics: 巳 (Sì) & 巳 (Sì)
When evaluating Snake (巳) and Snake (巳) in authentic Four-Pillar synastry (合婚), classical practitioners inspect which natal palace hosts the 巳–巳 vector (Companion Cohort (同气/自省) · 巳巳同气比和). 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 巳 anchors the 4th Lunar Month (Start of Summer · 立夏) command (09:00 – 10:59, South-Southeast (150°), Six-Harmony ally Monkey 申).
