Tai Ji Chuan is a unique body-building exercise developed on the basis of the traditional health-keeping methods of "induction" and "breathing". It advocates "guiding qi with intention and transporting the body with qi", and there are also exercise methods of practicing qigong and adjusting the heart. Thus, Tai Ji Chuan's internal boxing action was formed, with the close combination of consciousness, breathing and movement, and the unity of "practicing heart, qi and body" inside and outside, "starting with intention, then moving inside and then moving outside"; And form a unique boxing method that combines rigidity with softness, moderate speed, changing storage and development, and controlling internal strength. As a sport, Tai Ji Chuan has the function of health care. The secret lies in its "immobile" physical activity, which can stimulate all kinds of tissues and organs with a certain intensity and quantity, stimulate and promote a series of adaptive changes in physiology, biochemistry and morphological structure, and make the physique transform and develop in the direction of strengthening. For middle-aged and elderly people and patients with chronic diseases, it can delay the deterioration of the structure and function of various tissues and organs of the body, and can effectively play the role of fitness, treatment and delaying aging. Traditional Chinese medicine believes that man is an organic whole, which is connected from top to bottom by meridians, with internal and external communication, internal organs and external limbs. Tai Ji Chuan's unique practice method is beneficial to dredge meridians. First of all, we know that the sudden, intense and lasting stimulation of the seven emotions will lead to the disorder of human qi, the imbalance of qi and blood of viscera, yin and yang, and Tai Ji Chuan's emphasis on the relaxation of the whole body can weaken, transfer and overcome the stimulation of the seven emotions of internal injuries, thus facilitating the dredging of meridians. Secondly, Tai Ji Chuan's moderate and appropriate exercise will make the whole body warm and harmonious, increase the speed and intensity of meridian conduction, help pulse qi to run in the meridian system of the whole body, help the meridians to be unobstructed, make qi and blood fill the whole body, nourish viscera, nourish yin and yang, maintain and protect the body function, and increase the ability of disease resistance, evil resistance and self-repair. Thirdly, in the Tai Ji Chuan movement, the winding movement composed of waist rotation and limb flexion and extension has different pulling, squeezing and kneading effects on more than 300 acupoints all over the body. This is actually a kind of self-massage, which can play a similar role to acupuncture, activate meridians, stimulate the qi of meridians, dredge meridians, regulate excess and deficiency, strengthen the maintenance and contact of physiological functions of various tissues and organs, and make them in a coordinated and orderly state. Tai Ji Chuan attaches great importance to the health preservation of the unity of nature and man, and the unity of form and spirit. Tai Ji Chuan combines motion and static in exercise, which makes Tai Ji Chuan more in line with the fitness principle of moderate exercise. At the same time, Tai Ji Chuan's unique intention of calming the mind makes it easier to calm down, which can effectively block the interference and disorderly influence of excessive and intense seven emotions on qi and blood, and protect "Shen Yuan" from playing its normal role in regulating human physical and mental health. Tai Ji Chuan is a science with a long history and rich contents, which contains rich and unique practice methods. Tai Ji Chuan not only inherited the traditional way of keeping in good health in ancient China, but also developed it on the basis of modern science, which made it obtain greater health care efficacy in fitness, treatment and anti-aging, with special efficacy beyond drugs. This special effect is not out of reach. In practice, the following aspects must be achieved: First, the movements should be standardized, that is, the body posture should meet certain sports standards, which is also the action requirement of each formula, no matter how ever-changing the movements are. Only the standardization of body posture and movements is conducive to "obeying the will"; It is conducive to lengthening limbs, showing the characteristics of straightness, looseness, roundness and lightness more flexibly, resisting movement with quietness, seeking quietness while moving, and keeping the spirit inside, so as to make the boxing practice appear the virtual spiritual realm with only intentional movement and unconscious movement, and make the practice enter a higher level, and converge from the inside out and from the outside in order to achieve the unity of body and mind. To reach the standard of action, we must first be natural and relaxed physically, and at the same time be relaxed mentally, so as to achieve "body quietness". Tai Ji Chuan adopts abdominal breathing, which requires deep, even, thin, slow and long, but beginners should not deliberately pursue these, as long as they use smooth and natural breathing. Abdominal forward breathing is also the only way to realize abdominal reverse breathing, which will increase the regulation of somatic nervous system on breathing, thus having a better impact on the regulation of autonomic nervous system on visceral function. But beginners should not blindly adopt this breathing method, otherwise it will not only affect sports practice but also hold their breath. In fact, as long as the movements are skilled and the abdominal front breathing is more and more coordinated, it is just around the corner to realize abdominal reverse breathing. The philosophy of Taiji Chuan is natural and cannot be violated. Therefore, beginners must follow the principle of smooth breathing and avoid rushing for success. Tai Ji Chuan's good health care function can only be brought into play through long-term exercise. First of all, like other sports, the appearance of Tai Ji Chuan's exercise effect is a cumulative process, with the law of quitting without exercising. In addition, physical recovery and physical improvement is a slow process. As the saying goes, "getting sick like a mountain is like reeling", which is the truth. Tai Ji Chuan has the function of strengthening the body and treating diseases, but it has no immediate effect. Secondly, Tai Ji Chuan's health care function is the result of comprehensive exercise of "training body, mind and heart", and it is a long-term process to master the true meaning of Tai Ji Chuan. "Practicing 39 in winter and squatting in summer" just reflects the indispensability of practicing boxing. Third, practice has proved that Tai Ji Chuan's health care efficacy lies in persistent practice. Everyone who is determined to keep in good health by practicing Tai Ji Chuan should learn from it the truth of perseverance. The so-called "success is inevitable" is a process of self-defeating, and it is also a process of developing the habit of playing Tai Ji Chuan with growing interest. With this change, the sense of fullness, pleasure and happiness of physical and mental health will arise spontaneously, the quality of work and life will be unexpectedly improved, and the fun of life will be enjoyed more. Tai Ji Chuan's understanding and feelings about the three functions of fitness, treatment and anti-aging will be more profound. Then strengthen the confidence and interest in practicing boxing, and finally let Tai Ji Chuan become a mentor on the healthy road for practitioners.
