"Free-hand plastic surgery" is a kind of free-hand physiotherapy medicine that originated from the emperor of China, ancient Egypt and the royal family of Europe. Ge Hong's Elbow Emergency Prescription in Jin Dynasty is the earliest recorded method to repair mandibular joint dislocation in the world, that is, to repair crooked teeth, complete mouth or semi-extracted teeth by hand.

Later, I learned from studying human anatomy that the musculoskeletal nervous system is a unified whole, which restricts and influences each other. As long as the shape and function of one part change, it will lead to the adaptive changes of other parts and stimulate the natural regulation mechanism in our body. Therefore, we can adjust our body balance with the help of "freehand plastic surgery", which is an excellent health care method.

Take the head as an example, the skull is composed of 22 bone plates, and the bone itself is soft, otherwise the external pressure cannot be removed, so the bone will be deformed. Secondly, there are fascia and ligament between the plates, which can fine-tune the movement between the plates. Bone fragments need to rely on cerebrospinal fluid to supply nutrition, oxygen and water to the head along the spinal cord. If the cerebrospinal fluid is insufficient, it cannot be delivered to the head and face smoothly; Or when you come back, you get stuck in your neck because of cervical spondylosis or neck muscle strain, so the head and facial bones lack nutrition because of unbalanced nutrition, and then they are deformed and displaced.
