Which Small Intestine point is located on the dorsal aspect of the little finger, at the junction of the lines drawn along the ulnar border of the nail and the base of the nail, approximately 0.1 cun from the corner?

• A. SI 1
• B. HT 9
• C. SI 2
• D. HT 4

Answer: (A)

Precise point location using cun measurements is what this item tests. The Small Intestine Jing-well point sits on the dorsal aspect of the little finger, at the ulnar border of the nail, and about 0.1 cun from the corner of the nail. The described spot matches that exact location, so it is the correct point. The other options refer to different channels or locations (for example, Heart channel points near the fingertip or on the wrist), which do not fit the nail-corner, dorsal little-finger position described here.
