Which point is located at the corner of the forehead, 4.5 cun lateral to Shenting DU-24 and 0.5 cun within the anterior hairline?

Which point is located at the corner of the forehead, 4.5 cun lateral to Shenting DU-24 and 0.5 cun within the anterior hairline?

• A. St 1
• B. St 9
• C. Li 20
• D. St 8

Answer: (D)

The point tested is defined by two head landmarks and a measurement system using cun. Shenting (DU-24) sits on the midline at the hairline, and ST8 is described as being at the corner of the forehead, specifically 4.5 cun lateral to DU-24 and 0.5 cun within the anterior hairline. This places ST8 at the outer forehead near the temple, exactly where the description specifies. This precise location makes it the correct choice because it matches both the horizontal distance from DU-24 and the vertical position just inside the hairline at the forehead’s edge. Other points—one near the infraorbital region, another along the neck, and another beside the nose—occupy different regions and landmarks, so they don’t fit this combination of coordinates.
