Location
Behind the ear, at the centre of the mastoid process, at the junction of the middle and lower thirds of the curve formed by TE17 and TE20.
How to locate: Trace the curve behind the ear from TE17 (behind the lobe) up to TE20 (above the apex), close to the root of the auricle; the point is at the junction of its lower and middle thirds, in a palpable depression over the centre of the mastoid process, at about 8 o'clock on the right ear (4 o'clock on the left) with the apex at 12.
Distances are in cun, a proportional unit — how to measure.
