Which point on the abdomen is located 2 cun lateral to the midline and 3 cun superior to the umbilicus, level with Jiànlǐ REN-11?

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

Answer: (C)

Understanding how to locate abdominal points relies on two measurements we frequently use: how far from the midline (2 cun lateral) and how high above the navel (3 cun above the umbilicus). The point in question sits on the Stomach channel at a horizontal level that matches Ren-11 (the midline reference on the abdomen) and is 2 cun away from that midline on either side.

So, at the vertical position 3 cun above the umbilicus, and 2 cun lateral from the midline, this location corresponds to the Stomach point ST-22. This is why that option is the correct one: it matches the described coordinates exactly. To locate it in practice, find the umbilicus, go up 3 cun, then move 2 cun away from the midline to land on the Stomach channel at that level, which will be level with Ren-11. The other listed points would be at different vertical levels relative to the umbilicus, not at this exact coordinate.
