1.Respiratory system diseases: bronchitis, asthma, bronchiectasis, hemoptysis;
2.Others: stiff neck, diminished vision, shoulder and back pain, etc.

On the back, below the spinous process of the 7th cervical vertebra, 2 cun lateral to the midline. (This acupoint is paired, one on each side)

Sure, I will translate the provided steps into English:

Step 1: Sit with the head lowered or lie prone.
Step 2: On the posterior midline, you can see a prominent protrusion at the junction of the neck and back on the vertebrae.
Step 3: This protrusion, which can move with the neck's lateral movements, is the spinous process of the 7th cervical vertebra.
Step 4: Below the spinous process of the 7th cervical vertebra, at the location of Great Vertebra (GV-14) acupoint, move laterally by the width of two transverse fingers (the transverse diameter at the interphalangeal joint of the thumb is 1 cun) to find this acupoint.
