Geng's Facing Pair, And Where The Stems Sit In The Ring

Geng sits directly opposite mountain 7, Jia, twelve positions and a hundred and eighty degrees around the ring, the pairing compass school feng shui reads as a sitting-and-facing set for a building or a grave, back toward Geng and front toward Jia. Stephen Skinner's account of the luopan places the stem ring between the branch ring below it and the outer rings above, functioning as a finer division that lets a practitioner distinguish three fifteen-degree mountains within the thirty degrees a single branch alone would otherwise cover undivided; Geng is one of the two stem mountains flanking its sector's branch, sharing the sector's general direction while carrying its own distinct element and, through the Day Master reading, its own distinct temperament.

Because the eight stems on the ring pair up by element, Geng's own element partner sits in the mountain immediately across the same sector from it rather than opposite across the full circle, a closer, same-sector relationship compass school treatments keep distinct from the sitting-facing opposition proper. Compass school practice treats the fifteen-degree seam between one mountain and its neighbour as a genuine hazard rather than a rounding error: a sitting or facing line falling exactly on that boundary, called an empty or straddling line, is read as drawing on the qi of both adjacent mountains at once rather than cleanly on one, and Stephen Skinner's account of the luopan treats avoiding a seam-line reading as one of the instrument's basic disciplines, checked before any of the finer rings above the twenty-four mountains are consulted at all.
