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

• A. HT 9
• B. SI 2
• C. SI 3
• D. SI 1

Answer: (D)

This question tests precise point location on the Small Intestine channel, specifically the Nail bed or Jing-Well point on the little finger. The described spot—on the dorsal aspect of the little finger, at the ulnar border of the nail and base of the nail, about 0.1 cun from the nail corner—matches the classic location of the Small Intestine channel’s Jing-Well point. That tiny, exact position near the nail edge is what identifies this point. The other options don’t sit at that nail-edge location: they are on different parts of the finger or at other joints, so they don’t fit the described description.
