Above Zhiyang point is our sixth thoracic vertebra. Down the midline of the back, Dazhui is the last cervical vertebra of the human body, and then down is the thoracic vertebra. When you eat fish, you will find that after eating all the fish, it is a long bone with fishbones scattered on both sides. This fishbone is very similar to the bone behind the human body.
The bones on the back are arranged regularly in this way. The space between two thorns is hollow in the human body, just like the valley between two mountains.
