Which point is on the lower leg, midway between the tibio-femoral joint line and the lateral malleolus, one finger-breadth lateral to the anterior crest of the tibia?

• A. ST 37
• B. ST 38
• C. ST 39
• D. ST 36

Answer: (A)

Locating points on the stomach channel uses clear leg landmarks and a consistent offset from the tibia’s anterior crest. This point sits on the lower leg, about halfway between the knee joint line and the lateral malleolus, and it is one finger-breadth lateral to the anterior crest of the tibia. That specific spot corresponds to Shangjuxu on the stomach channel. It’s higher than the points that sit closer to the ankle and lower than those near the knee, so it matches the halfway-down location described. To find it, relax the leg, feel along the line just to the outside of the tibial crest and move downward from the knee until you reach roughly the midpoint to the ankle; you’ll locate a shallow hollow there.
