Which point is on the medial side of the upper leg, 6 cun proximal to Xuèhǎi SP-10, on a line connecting Xuèhǎi SP-10 with Chōngmén SP-12?

• A. SP 11
• B. SP 10
• C. SP 9
• D. SP 12

Answer: (A)

The key idea is tracing the Spleen channel up the medial thigh and using a 6-cun step from Xuèhǎi (SP-10) toward Chongmén (SP-12). Six cun above SP-10 along that line places SP-11 on the medial side of the upper leg. So the point located there is SP-11. SP-12 lies below toward the groin, SP-10 is the reference point itself, and SP-9 is on the lower leg, not the upper thigh.
