On the lateral side of the chest, along the mid-axillary line, at the sixth intercostal space. (This acupoint is bilateral, one on each side.)

Step 1: Sit upright with your side facing forward or lie on your back.
Step 2: Starting from the nipple, feel downward through two intercostal spaces (the nipple is approximately level with the fourth intercostal space).
Step 3: The intersection of this intercostal space with the mid-axillary line (a vertical line drawn downward from the midpoint of the armpit) is the location of the acupoint.
