Which GV point is at the top of the head on the midline, 0.5 cun posterior to the anterior hairline and 0.5 cun anterior to Shàngxīng DU-23?

• A. GV 27
• B. GV 22
• C. GV 24
• D. GV 23

Answer: (C)

The position being tested is a midline, anterior-vertex point on the Governing Vessel that sits just behind the frontal hairline and slightly in front of another midline point (DU-23). This exact spot corresponds to the GV-24 location. GV-24 lies on the head’s midline in the frontal–crown region, about half a cun behind the hairline, placing it between the hairline and DU-23. That precise relationship—0.5 cun posterior to the anterior hairline and 0.5 cun anterior to DU-23—defines GV-24. The other points on the list sit in different spots along the midline or toward other regions of the head, not at this transitional front-midline location.
