Which LU point is 4 cun below the axillary fold?

• A. LU-4
• B. LU-1
• C. LU-6
• D. LU-5

Answer: (A)

Lung point locations are often given in cun using the axillary fold as a reference line, so you measure downward from that fold along the chest and arm. Four cun below the axillary fold is the Lung point that sits in the upper chest along the Lung channel. This point is described specifically as being four cun below the armpit crease, which distinguishes it from other Lung points that lie at the elbow or forearm, or higher on the chest. The elbow-area point and the forearm point sit in lower or different landmarks, and another chest point sits higher up rather than four cun below the fold.
