Which point is 3 cun distal to LI 11 on the line LI-11-LI-5?

• A. LI 9
• B. LI 8
• C. LI 6
• D. LI 4

Answer: (A)

Distance along a meridian is measured in cun, and the LI channel runs from LI-11 at the elbow toward LI-5 at the wrist. The line LI-11-LI-5 traces down the outer forearm toward the wrist, so locating a point three cun distal from LI-11 along that line brings you to LI-9. This is why LI-9 is the correct pick. The other locations sit on different points along the channel or at different distances from LI-11, so they do not occupy that exact three-cun mark on this line.
