Which point is located on the lower abdomen, 4 cun lateral to the midline, level with Guānyuán REN-4?

• A. M-UE-1 SHÍXUĀN
• B. N-CA-4 TÍTŪO
• C. M-UE-24 LUÒZHĚN
• D. M-UE-29 ÈRBÁI

Answer: (B)

Measuring from the midline using the Ren channel as the vertical reference, Tituo sits on the lower abdomen 4 cun lateral to the midline at the same horizontal level as Guanyuan (Ren-4), which is about 3 cun below the umbilicus. This exact combination of vertical level and lateral distance defines Tituo, so it matches the description in the question. The other named points lie in different regions (not on the lower abdomen at that height), so they do not fit the specified location.
