The Tianzong point is an acupoint of the Hand Sun and Small Intestine meridian, which is on the back of the shoulder, that is, in the scapular gland. When taking this point, first feel the lower edge of the scapula, the lowermost tip, up to the scapular gland, which is the hard bone called the scapular gland when you turn your hand over, and at the midpoint of the scapular gland and 1/3 of the line between the scapular angle is the Tianzong point. As long as you feel the scapular gong and the subscapular angle to the midpoint of the scapular gong, as long as you feel these two points, you can quickly find the 1/3, which is a very fast way to get the point. The Tianzong point is very effective for pain in the scapula as well as chest tightness and shortness of breath, below the scapula, which is a relatively very safe point.
