Which BL point is 1.5 cun posterior to BL-7 and 5.5 cun within the anterior hairline, 1.5 cun lateral to the midline?

Which BL point is 1.5 cun posterior to BL-7 and 5.5 cun within the anterior hairline, 1.5 cun lateral to the midline?

• A. BL-7
• B. BL-9
• C. BL-8
• D. BL-6

Answer: (C)

In this area of the head, points on the Bladder channel are located using landmarks like the anterior hairline, the midline, and standard cun measurements. The description places the target behind BL-7 by 1.5 cun along the same horizontal line and offset 1.5 cun to the side of the midline, with the line being about 5.5 cun back from the hairline toward the forehead region. This combination precisely corresponds to BL-8, which sits just behind BL-7 and off the midline in the frontal region. The other points sit at different transverse positions or different distances from the hairline, so they don’t fit both coordinates.
