Danzhong (CV17)
Mid-sternum / cardiac region — Conception Vessel point
Danzhong is CV17 on the anterior midline of the sternum, in the precordial or cardiac region. The coordinate is a broad body projection rather than a claim that the point lies on the heart; dian xue texts use chest-centre language variably, while wuxing_five_zang supplies the separate heart/fire organ context.

Dianxue / shixue passages in classical quan pu (primary_canonical)
Ming–Qing dianxue/shixue quan pu, in heterogeneous point-striking passages concerning cv17 danzhong, preserves a martial vulnerability vocabulary and lineage claim; contested attribution means it is not a single canonical chart or a clinically validated effect.
Huangdi Neijing · Lingshu (primary_canonical)
Lingshu ch. 10 (Jing mai) gives the Ren Mai chest-midline course at Danzhong (CV17); the modern alphanumeric point identity and dianxue application are later nomenclatures, so this passage supports channel topography rather than a martial effect.
