Qigong is a unique fitness technique in China. Basically divided into two categories, one is static, standing still, sitting still or lying still, so as to concentrate, breathe in a special way, and promote the functions of circulation, digestion and other systems. The other is mainly about exercise, generally adopting moderate exercise, massage and other methods, and insisting on regular exercise to enhance physical fitness. In ancient times, according to different techniques, they were called breathing, guiding, activating qi, convincing, eating qi, practicing qi, sitting still, meditation or internal work. Its characteristic is to combine mind, spirit and body through the subjective efforts of practitioners, so as to achieve the purpose of fitness and disease prevention. Interpretation of Qigong 1 Qigong has a long history in China. In ancient times, the contents of Qigong were usually called spitting, guiding, moving qi, persuading, alchemy, cultivation and meditation. The word "Qigong" is rarely used in ancient books, and it is occasionally mentioned, and there is no complete explanation. Until 1950s, Liu wrote in the book "The Practice of Qigong Therapy": "The word' Qi' here stands for breathing, and the word' Gong' is the practice of constantly adjusting breathing and posture ..." It is generally believed that the word "Qigong" has been confirmed and spread since then. Some foreign materials have translated Qigong into "deep breathing exercise", and some domestic reference books have also been copied. Obviously, the true meaning of Qigong has not been realized. In fact, qigong exercise includes three means: breathing, posture and mind, and each means has a variety of exercise methods. Deep breathing is just one of many breathing exercises. It can be seen that it is too one-sided to interpret the definition of Qigong as "deep breathing exercise". If we define Qigong from the perspective of traditional Chinese medicine, Qigong is an exercise method that makes people's qi coordinate through self-exercise. With the development of science, we can use the relevant knowledge of modern science to understand Qigong, which will further deepen our understanding of the nature of Qigong. From the perspective of modern behavioral medicine, Qigong exercise is a behavioral therapy that studies and trains a benign behavior that is beneficial to physical and mental health through conditioned reflex and finally fixes it. From the psychological and physiological process of Qigong's function, Qigong can be defined as a self-exercise method, which mainly uses self-suggestion as the core means to promote consciousness to enter a state of self-hypnosis, and adjust the balance of body and mind through the psychological-physiological-morphological self-adjustment mechanism to achieve the purpose of fitness and treatment. We can also sum up the above knowledge in one sentence: Qigong is a kind of self-psychosomatic therapy with China national cultural characteristics. There are many kinds of psychosomatic therapies. Qigong is different from many other self-psychosomatic therapies in that it has the national cultural characteristics of China-a kind of practical activity that is unique to China people and guided by the theoretical content of "regulating the mind" of traditional Chinese medicine. Explanation of Qigong 2 Qigong has a history of thousands of years in China. The word Qigong first appeared in Xu Xun's Ling Jian Zi in the Jin Dynasty. Although Qigong here means practicing Qi and Xiu De, it is not used as a special term. It was not until the late Qing Dynasty that the word Qigong was clearly put forward in the definition of Qigong in the book "The Secret of Shaolin Boxing". It was not until 1953 that Liu named his martial arts "Qigong Therapy", and later established a Qigong sanatorium and wrote books such as "Qigong Therapy Practice" that the word Qigong was widely used and known by the masses. In the late 1970s and early 1980s, Qigong has developed into a special knowledge established by people. What is Qigong? At present, there are dozens of standardized definitions of it. Although each has its own reasons and basis, it has not been recognized by everyone. Based on the connotation of the definition of Qigong, intelligent Qigong is defined as: "Qigong is an exercise that transforms, perfects and improves human life function through active and introversive conscious activities (adjusting the heart, body and breath is its extension), and transforms natural instinct into conscious intelligence." This definition points out the theoretical basis of Qigong-the holistic view of life, including that the universe and nature are a whole, man himself is a whole, and man and nature are a unified whole (harmony between man and nature), and its holistic view of harmony between man and nature is the theoretical basis of all Qigong. It is pointed out that the special exercise method of Qigong-the exercise of active introversion using consciousness, that is, the concentration and singleness of mental activities and the combination with one's own life activities, is the fundamental essence of Qigong exercise which is different from other exercise methods and the soul of Qigong definition. The purpose of qigong exercise is clear-to transform, perfect and improve people's life function, get rid of the bondage of natural instinct and enter the free kingdom of consciousness and intelligence; It is pointed out that Qigong is a practice of using Qigong to improve one's body and mind and improve one's life function-Qigong is a practical knowledge, and the process of Qigong exercise is a practical process of using Qigong science to transform and sublimate oneself. This definition summarizes all the connotations of Qigong and is a complete scientific definition that meets the requirements of modern scientific norms. Explanation of Qigong 3 Qigong is a physical and mental exercise method with the purpose of regulating heart, qi and body, preventing and treating diseases, strengthening body and prolonging life, and developing potential. Self-adjustment means adjusting psychological activities, breathing movements, body posture and movements. These three tones are the basic methods of qigong exercise and the three major elements or basic norms of qigong discipline. The original qigong has no name, and the latter part is called "dance". For example, in Lu's Spring and Autumn Annals, "The bones and muscles can't be contracted, so dance is used to promote them". During the Spring and Autumn Period and the Warring States Period, Qigong was summarized as "guiding on stilts", such as "flaccidity, cold and heat should be guided on stilts" in Su Wenyi's Treatise on Prescriptions and Medicine, while meditation, fetal interest, moving qi, convincing, regulating qi, Sunday, Neidan, etc., which are scattered in famous works of all ages, also belong to Qigong. As for the word "Qigong", it was first seen in the Ming History by Xu Xun, a Taoist priest in the Jin Dynasty. Even the later works are the Sui and Tang Dynasties at the latest. The book Qi Jing, which appeared after the Sui and Tang Dynasties, recorded that "Qigong is wonderful, and the way of Qigong is similar ...", but its connotation is not completely in line with what we are talking about now. Qigong, which is widely used now, was gradually popularized after the establishment of Beidaihe Qigong Sanatorium in the 1950s. Qigong is gradually formed in people's practice in production, life and medical treatment. Qigong therapy and exercise therapy are both related and different. Exercise therapy can include exercise therapy, but exercise therapy cannot replace Qigong therapy. Physical exercise is always just one of the means of qigong to adjust the heart, and breathing exercise is also for adjusting the heart. The three tones are a unified whole and must be centered on the adjustment of the heart. The combination of internal training and external training, mainly internal training. Qi in qigong refers to "internal qi" and "true qi", which has a deeper meaning. Qigong therapy has comprehensive characteristics, at least it is a combination of psychotherapy and physical therapy. Qigong therapy includes psychotherapy, but it is different from psychotherapy. Psychotherapy generally refers to the use of language, expression, posture and attitude by doctors. Reasoning patients who are awake and proposing treatment suggestions; Or use some special induction methods to induce a hypnotic state that is somewhat similar to superficial sleep, and then give treatment suggestions to patients under hypnosis. Therefore, patients are always passive. Qigong therapy is characterized by giving full play to patients' subjective initiative. Under the guidance of doctors, patients can strengthen their self-control ability through self-exercise. Qigong is essentially different from religion. Qigong, as a science, does not involve the purposes and teachings of various sects, but only extracts scientific connotation from the practice of believers. This is reflected in the Taoist scriptures and Buddhist scriptures, which also record a lot of information about ancient Qigong. In addition, some theories in religion are often used for reference by practitioners.
