according to Chinese medicine, a meridian that runs in front of the human body is called ren meridian, which is the "commander" to regulate the qi and blood of the whole body. Some people call it "the sea of yin veins", which is closely related to some special physiological activities of women. Inability of ren meridian can be manifested as irregular menstruation, infertility due to amenorrhea, abnormal leucorrhea, abdominal distension and pain, etc. Deficiency and failure of ren meridian can be manifested as restless fetal movement, even abortion, delayed menstruation or amenorrhea, or endless menstruation.

The main treatment scope of Shanzhong point can be summarized into two aspects, cardiopulmonary diseases and breast system-related diseases. Because it belongs to Ren meridian and is close to the breast, it is a necessary acupoint for the prevention and treatment of breast system-related diseases. Therefore, it is one of the "key points in gynecology". In addition, modern people use the method of infrared radiation spectrum scanning on the body surface to confirm that the infrared radiation intensity of Shanzhong point is lower than that of other places in patients with mammary gland hyperplasia, which suggests that Shanzhong point is a special reaction point of mammary gland hyperplasia.

Some diseases related to female mammary system appear in lactation, such as mastitis and postpartum hypogalactia; Some appear before and after menstruation, such as breast pain during menstruation; The most common diseases are hyperplasia of mammary glands and breast cancer. Here, female friends should be reminded that if they find uncomfortable or abnormal conditions, they must go to the hospital for examination and diagnosis, so as not to delay their illness.
