How to find

While BL 03 (Eyebrow’s Pouring) is still located on a vertical line through the inner canthus of the eye, BL-04 is located slightly more laterally (hence its name). The distance of 1.5 cun from the midline refers to the proportional cun measurements along the anterior hairline: the distance between GV 24 (Courtyard of the Spirit) (on the midline) and ST 08 (Head’s Binding) (on the corner of the forehead) is 4.5 proportional cun; therefore, the distance between BL-04 and the midline is one third of this distance.Located on the same level (0.5 cun within the anterior hairline) are GV 24 (Courtyard of the Spirit) (on the midline), BL 03 (Eyebrow’s Pouring) (superior to the inner canthus of the eye), GB 15 (Head Governor of Tears) (on the pupil line), GB 13 (Spirit Root) (3 cun lateral to the midline) and ST 08 (Head’s Binding) (on the corner of the forehead).

Location

0.5 cun superior to the anterior hairline and 1.5 cun lateral to the midline (or one third of the distance between GV 24 (Courtyard of the Spirit) and ST 08 (Head’s Binding)).
