Which GB point lies 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 12
• C. GB 14
• D. GB 15

Answer: (A)

The distance and landmark clues identify a very specific forehead point on the Gallbladder channel. Being “on the forehead, 0.5 cun within the anterior hairline” places the point just inside the hairline on the forehead. The additional instruction that it lies “two thirds of the distance between Shéntíng DU-24 and Tóuwéi ST-8” pinpoints the exact spot along the line connecting those two reference points. That particular combination of hairline position and the two-thirds proportion is the standard description for GB13, so this is the best match. The other options don’t fit this precise description, as they are described at different forehead/temple locations on the Gallbladder meridian and are not defined by this hairline plus two-thirds distance rule.
