Which point lies on the forearm 4 cun proximal to Dàlíng P-7 on the flexor aspect?

• A. M-UE-29 ÈRBÁI
• B. M-UE-46 ZHǑUJIĀN
• C. N-CA-4 TITŪO
• D. M-UE-1 SHÍXUĀN

Answer: (A)

Distances along the forearm using cun measurements place points in a specific order from the wrist toward the elbow. Da-ling (P-7) sits at the wrist on the flexor aspect, and moving four cun proximally along the inner forearm brings you to Èrbái. This location matches the description of lying on the flexor forearm at about four cun from Da-ling, making it the correct choice. The other points are not situated in that same forearm region at that distance from PC-7; they lie in different areas or at different distances.
