Point name meaning:

This point is important in the treatment of hearing disorders. Combined with its location in front of the ear, this accounts for the name Auditory Convergence. (guān) in the alternate names for GB-1 and GB-2 could be translated as joint, pass or gate. In all cases, it is probably a reference to the mandibular joint (see GB-3).
