Directly superior to Zan Zhu BL-2, 0.5 cun within the anterior hairline, level with Shenting DU-24.

• A. BL 3
• B. BL 2
• C. BL 4
• D. BL 1

Answer: (B)

The key idea is locating the Bladder channel points around the eyebrow using clear facial landmarks. Zan Zhu (BL-2) sits at the medial end of the eyebrow near the inner canthus. When you describe a point as being 0.5 cun within the anterior hairline and level with Shenting (DU-24), you’re using Shenting as a horizontal reference on the forehead and identifying a spot at the inner eyebrow region. That positioning corresponds to Zan Zhu, the BL-2 point, which is the eyebrow-point closest to the inner corner of the eye and sits at the hairline level.

So this description matches BL-2 because BL-2 is the point at the inner end of the eyebrow, aligned with the hairline and roughly level with DU-24. The other nearby eyebrow/forehead points occupy different positions along the brow or higher on the forehead and are described with different landmarks.
