Which GV point is located at the back of the head on the midline, 1.5 cun directly superior to Qiángjiān DU-18 and 1.5 cun posterior to Baihuì DU-20?

Which GV point is located at the back of the head on the midline, 1.5 cun directly superior to Qiángjiān DU-18 and 1.5 cun posterior to Baihuì DU-20?

• A. GV 18
• B. GV 19
• C. GV 20
• D. GV 21

Answer: (B)

This question tests how you locate Governing Vessel points along the head using standard cun measurements from known landmarks. The Governing Vessel runs along the midline, and on the head the key reference points are Baihui (the vertex) and the occipital midline point (often noted near the area of Qiángjiān). The described location is on the midline of the back of the head, 1.5 cun behind Baihui (DU-20) and 1.5 cun above Qiángjiān (DU-18). That precise combination of distances places the point at GV-19. The other points lie at different positions along the midline and don’t fit both distance requirements.
