Which LI point is located 1 cun proximal to and 1 cun lateral to LI-11 when the elbow is flexed?

• A. LI-12
• B. LI-11
• C. LI-10
• D. LI-13

Answer: (A)

Think about how the LI points around the elbow are laid out in relation to LI-11. LI-11 sits at the elbow crease on the lateral side when the elbow is flexed. The point described as being 1 cun proximal (toward the shoulder) and 1 cun lateral (toward the outer side of the arm) to LI-11 is LI-12. So you locate LI-11 first, then move one cun up and one cun out to find LI-12. The other options don’t occupy that exact diagonal offset from LI-11, so they don’t fit the description.
