Ce Ying San He (側映三合) — the lateral-mapping variant of San He. Applies the three-harmony triads from oblique directions, accounting for terrain asymmetry where the primary dragon or water arrives from a non-cardinal angle.

Ce Ying San He 側映三合
Ce Ying San He (側映三合) — Lateral Mapping Three Harmonies — is an advanced variant of the San He school for sites where primary landform features do not arrive from standard cardinal or intercardinal directions. Instead of forcing the site into a rigid directional framework, Ce Ying maps the three-harmony triad laterally, allowing oblique dragon and water vectors to be assessed against the sitting-facing axis through a rotational projection.

When Ce Ying Applies 適用場景
- ·Dragon arrives from an oblique (non-standard mountain) direction
- ·Water ingress angle diverges more than 15° from the cardinal position
- ·Site constrained by terrain with non-orthogonal features
- ·Standard San He analysis yields conflicting elemental triads
- ·Multiple water sources arrive from different vectors
- ·Complex urban sites with irregular lot orientation
