Which GB point is on the forehead, 0.5 cun within the anterior hairline, two thirds of the distance between Shéntíng DU-24 and Tóuwéi ST-8?

Which GB point is on the forehead, 0.5 cun within the anterior hairline, two thirds of the distance between Shéntíng DU-24 and Tóuwéi ST-8?

• A. GB 13
• B. GB 14
• C. GB 15
• D. GB 16

Answer: (A)

The essential idea here is precise point location using anatomical landmarks and measurements on the forehead. The description specifies a spot that is 0.5 cun inside the anterior hairline and sits two thirds of the way along the line from Shéntíng (DU-24) to Tóuwéi (ST-8). That exact combination points to a single Gall Bladder point on the forehead: GB13. GB13 sits on the GB channel in the frontal region at that coordinate, which is why it’s the correct choice. The other forehead GB points are located at different heights or positions along the forehead and do not align with that two-thirds distance from DU-24 to ST-8, so they don’t match the given description.
