Which point is on the flexor aspect of the forearm, 4 cun proximal to Dàlíng P-7, either side of the tendon of flexor carpi radialis?

• A. M-UE-46 ZHǑUJIĀN
• B. M-UE-29 ÈRBÁI
• C. N-CA-4 TITŪO
• D. M-UE-24 LUÒZHĚN

Answer: (A)

Locating a point this way relies on two landmarks: a fixed distance up the forearm from Da-ling (PC7) and the nearby tendon that serves as a guide. Four cun up the flexor (palm-side) aspect of the forearm, with the point flanking the tendon of the flexor carpi radialis, points to a very specific spot. The name ZHǑUJIĀN corresponds to that precise location on the forearm, on either side of the FCR tendon, about four cun proximal to PC7. The other options do not sit at this exact location on the flexor forearm near the FCR tendon, so they aren’t correct for this description.
