Which point is located at 1 cun lateral to the mental foramen and near the chin area?

Explanation:
Locating a point 1 cun lateral to the mental foramen depends on using a clear facial landmark on the lower jaw. The mental foramen is the opening on the mandible where the mental nerve exits; from that landmark, moving 1 cun to the side places you on the body of the mandible in the chin region. That precise spot is the point JIĀCHÉNGJIĀNG (M-HN-18), which is why it’s described as being near the chin. Clinically, this area targets the lower face and jaw. The other options occupy different regions—one near the upper lip center, another near the nasal area, and another in a different head region—so they don’t match the chin-area location described.
