Which point is the apex of the equilateral triangle on the lower abdomen?

• A. M-CA-23 SĀNJIǍOJIǓ
• B. N-CA-4 TÍTŪO
• C. M-UE-1 SHÍXUĀN
• D. M-UE-24 LUÒZHĚN

Answer: (A)

The main idea is that certain lower-abdominal points are located by a geometric cue—a visible apex formed by an equilateral triangle on the abdomen. The apex corresponds to a specific point on the San Jiao (Triple Burner) channel. The name SĀNJIǍOJIǓ identifies that San Jiao point, and the accompanying code M-CA-23 is simply the dataset’s way of listing that exact point. So this option matches the apex-of-the-triangle concept on the lower abdomen. The other names point to different points or different channels, so they don’t correspond to the apex of that abdominal triangle.
