Which point lies between the ring and little fingers, 0.5 cun proximal to the margin of the web?

• A. PC 9
• B. SJ 2
• C. PC 3
• D. PC 7

Answer: (B)

Focus on the precise location along the San Jiao channel on the dorsum of the hand. The spot between the ring and little fingers, 0.5 cun proximal to the margin of the web, sits in the web-between area specific to the San Jiao line and is identified as San Jiao point two. That exact description—between the fourth and fifth fingers, just proximal to the web margin on the dorsum—matches this point, making it the correct choice. The other options lie in different areas: one is at the tip of the middle finger, another is at the elbow crease, and another at the wrist, none of which correspond to the described web-space location.
