Between the fourth toe and the little toe, 0.5 cun proximal to the margin of the web?

• A. GB41
• B. LV1
• C. GB43
• D. GB43

Answer: (C)

The key idea is precise toe-web anatomy and cun measurement: identify the web between the fourth and little toe, then move 0.5 cun toward the ankle. The point located there on the dorsum of the foot is Gall Bladder 43 (Xiaxi). This spot sits in the small depression between those toes, at about half a cun proximal to the web margin.

The other options don’t fit this specific web-space location. One is on the big toe area, another is near a different part of the foot, so they don’t correspond to the described position between the fourth and little toes.
