Which point is between the fourth toe and the little toe, 0.5 cun proximal to the margin of the web?

• A. GB44
• B. GB40
• C. LV1
• D. GB43

Answer: (D)

The main idea is knowing the exact spot on the foot where a point on a channel lies in relation to the toe webs. Between the fourth and little toes, 0.5 cun proximal to the web margin sits on the Gallbladder channel at a point called GB-43 (Xiaxi). That precise location—between the 4th and 5th toes, just 0.5 cun toward the dorsum from the web edge—defines this point, which is why it’s the correct choice.

Other options don’t share this exact interdigital location. One lies at the big toe side (Liver point on the big toe), and another is an ankle point along the Gallbladder channel, not near the toe web. The remaining point is associated with different toe-area positioning, so it doesn’t match the described site.
