Which BL point is described as one third of the distance between Shenting DU-24 and Towei ST-8?

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

Answer: (C)

The location is determined by dividing a line between two anatomical landmarks into equal parts and identifying the BL point that sits at the specific fraction. For the forehead route from Shenting (DU-24) at the midline of the forehead to Touwei (ST-8) near the temple, the standard method places BL points along that line at set fractions. The point described as one third of the distance from DU-24 to ST-8 falls at the first third, which corresponds to Bladder point BL-3. So BL-3 is the point located about one-third of the way from Shenting to Touwei on this forehead line.
