On the ventral side of the forearm, on the radial side, along the line connecting Cubit Marsh (LU-5) and Great Deep Pool (LU-9), 7 cun above the wrist transverse crease. (This acupoint is bilateral, one on each side.)

Extend the arm with the palm facing to the side. First, determine the positions of Cubit Marsh (LU-5) (refer to "Cubit Marsh") and Great Deep Pool (LU-9) (refer to "Great Deep Pool"). Measure 1 horizontal finger width upward from the midpoint of the line connecting Cubit Marsh and Great Deep Pool, on the medial edge of the radius, and that is the location of this acupoint.
