Renying (ST9)
Carotid groove — Stomach channel point, right representative
Renying is ST9 in the lateral neck groove beside the laryngeal prominence, and it is bilateral; the right side is the displayed anchor. Its location overlaps major neurovascular structures, so the martial association is recorded as a hazardous anatomical reference and not as an instruction or claim of reliable incapacitation.

Dianxue / shixue passages in classical quan pu (primary_canonical)
Ming–Qing dianxue/shixue quan pu, in heterogeneous point-striking passages concerning st9 renying, preserves a martial vulnerability vocabulary and lineage claim; contested attribution means it is not a single canonical chart or a clinically validated effect.
