San He 三合
San He (三合) — Three Harmonies — is one of the two major schools of classical Feng Shui. It analyses landform (巒頭) and the relationship between dragon (龍), water (水), sitting mountain (坐向), and graves/gates (穴/門) using the twelve earthly branch harmonies. The three branches of each elemental triad must align with the dragon, water ingress, and sitting direction to create a complete harmonic circuit.

Core Principles 核心原則
Dragon 龍法
Trace the mountain dragon to its growth point (長生位) — this determines the elemental frame of the site.
Water 水法
Water must enter from the Growth (長生) position of the dragon's element and exit at the Tomb (墓庫) gate.
Sitting 坐向
The sitting mountain must align with one of the three harmonious branches of the identified elemental triad.
Verification 驗証
All three — dragon origin, water ingress, and sitting direction — must confirm to the same triad for a complete San He circuit.
