On the back, below the spinous process of the 7th thoracic vertebra, 1.5 cun lateral to the midline. (This acupoint is bilateral, one on each side.)

Step 1: Lie prone or sit up straight;
Step 2: Determine the lower angle of the scapula when the upper arm hangs naturally against the chest wall;
Step 3: The intersection of the line connecting the lower angles of both scapulae with the posterior median line is at the 7th thoracic vertebra;
Step 4: There is a depression below the spinous process of the 7th thoracic vertebra, and 2 horizontal fingers lateral to this depression (place the index and middle fingers side by side, using the width of the middle finger's proximal interphalangeal joint as the standard for 1.5 cun) is the location of this acupoint.
