What is the simplest way to locate Dazhui (a specific acupuncture point)?

Dazhui usually refers to Dazhui acupoint. The Dazhui acupoint is mainly located on the posterior midline of the human body, in the depression below the spinous process of the seventh cervical vertebra. When you bow your head, the highest vertebral body at the junction of the neck and back, with a depression at its lower edge, is the Dazhui acupoint. The Dazhui acupoint belongs to the Governor Vessel (Du Mai), mainly located at the back of the neck. Acupuncture at the Dazhui acupoint can achieve the effects of clearing heat and resolving exterior syndromes, intercepting malaria, and stopping headaches. It can assist in the treatment of febrile diseases, cough, wind rash, acne, infantile convulsion, ankylosing spondylitis, and other conditions. Following medical advice for massage or acupuncture performed by a doctor usually does not have a significant impact on the patient's health. Before treatment, the skin at the acupoint needs to be disinfected, and the instruments used also need to be sterilized, which can reduce the probability of skin and body infections. If symptoms such as skin itching, red rash, redness, pain, blisters, etc., occur after treatment, inform the doctor promptly and take reasonable treatment measures. In daily life, it is necessary to develop a good lifestyle and not put too much pressure on oneself. Engage in physical exercise according to one's actual condition, such as running and rope skipping, to strengthen the body and promote the excretion of toxic substances in the body.
