《灵枢·经脉》：胆足少阳之脉，起于目锐眦，上抵头角，下耳后，循颈，行手少阳之前，至肩上，却交出手少阳之后，入缺盆。

    The Chapter "Discussion on the Meridians" in Miraculous Pivot says: The Gallbladder Meridian starts from the outer canthus, ascends to the corner of the forehead, then curves downward to the retroauricual region and rounds along the side of the neck in front of the Triple Energizer Meridian to the shoulder, then turns back, transverses and passes behind the Triple Energizer Meridian, down to the supraclavicular fossa.

    The branch arises from the rectroauricular region and enters into the ear. It comes out and passes the preauricular region to the posterior aspect of the outer canthus. ......
