Which point is located approximately 0.5 cun anterior to the upper border of the root of the ear, in a slight depression on the posterior border of the hairline of the temple?

• A. SJ 23
• B. SJ 20
• C. SJ 22
• D. SJ 21

Answer: (C)

Understanding the temple region and the San Jiao channel helps identify this point. The description points to a shallow depression right at the posterior border of the hairline of the temple, about 0.5 cun in front of the upper border of the ear root. That precise spot is a San Jiao point located there, on the temple’s hairline border. The other nearby locations lie in different landmarks around the ear or temple and do not match this exact depression in the temple hairline, so they aren’t correct for this description.
