Which point is on the abdomen 2 cun lateral to the midline and 2 cun superior to the umbilicus, level with REN-10?

• A. ST 20
• B. ST 21
• C. ST 23
• D. ST 22

Answer: (C)

This question is about locating abdominal points using precise cun measurements relative to the midline and the umbilicus, with a cross-check on the Ren meridian line. The described spot is 2 cun lateral to the midline and 2 cun above the umbilicus, which places it on the stomach channel in the upper abdomen and on the same horizontal plane as Ren-10. That exact coordinate corresponds to Stomach 23.

Why this fits best: Stomach 25 sits level with the umbilicus, and moving up the line a couple of cun places you at Stomach 23, which is 2 cun above the umbilicus and 2 cun lateral to the midline. The other options are at different vertical levels and thus do not match the specified distance from the umbilicus, even if they share the same lateral offset. So the described position aligns precisely with Stomach 23.
