Which HT point is on the dorsal aspect of the little finger, on the radial border of the nail and base of the nail, approximately 0.1 cun from the corner of the nail?

• A. HT 9
• B. HT 8
• C. SI 4
• D. SI 2

Answer: (A)

The question is testing precise fingertip location for the Heart channel’s Jing-Well point. Jing-Well points sit at the tips of the fingers on yin channels, and the Heart channel ends at the tip of the little finger. The Heart Jing-Well point is located at the very fingertip on the radial (thumbward) border of the nail, at the base of the nail, about 0.1 cun from the corner of the nail. That description matches the given location: dorsal aspect of the little finger, on the radial border of the nail and base of the nail, near the nail corner.

The other points are located elsewhere: one is on the wrist/palm side, not at the fingertip; another sits at the base of the hand near the wrist, and the last is on the little finger but not at the nail area. So the fingertip nail-bed location uniquely identifies the Heart Jing-Well point.
