Which GB point is located 0.5 cun anterior and inferior to GB-27?

• A. GB 27
• B. GB 28
• C. GB 26
• D. GB 25

Answer: (B)

The important idea here is how points along a meridian are spaced and located relative to each other. On the Gall Bladder channel in the lower torso, adjacent points are defined by small, precise distances, commonly 0.5 cun apart. If a point is described as being 0.5 cun anterior and inferior to another, you move a half-cun forward (toward the front of the body) and downward from the reference point along the channel. That specific relation places the next point just in front and below the previous one.

Therefore, the point that sits 0.5 cun in front and below GB-27 is GB-28. So the correct choice is the one that lies ahead and downward from GB-27 along the same line, which matches this 0.5 cun anterior-inferior relationship. In practice, you locate GB-27 first, then move slightly forward and down to find GB-28.
