Some theories and practices of yoga are strikingly similar to those of traditional Chinese medicine in China, such as Yin and Yang, Qi and blood, viscera and meridians. In the long history of cultural exchange, there is no record of the influence of yoga on China's ancient philosophy and traditional Chinese medicine. Therefore, the similarity of the basic understanding of human life activities between ancient civilizations in the Ganges River basin and the Yellow River basin is a mystery that modern scholars should pay attention to and uncover. Yoga and Chinese medicine have the same health care wisdom, and yoga also attaches importance to the balance of yin and yang. The most important thing in China's medical culture is the harmony of Yin and Yang in the four seasons, especially in Neijing, which puts forward that the harmony between man and nature should be adjusted according to the changes of the four seasons. It is mentioned in the book that Yang is nourished in spring and summer, and Yin is nourished in autumn and winter. Comparing people with the small universe, it is advocated that the small universe should conform to the laws of the big universe and the four seasons. This shows that the human body and nature are integrated, so the four seasons alternate, bloom flowers fall, personnel turnover, and the creatures in nature are constantly influenced by the climate of wet spring, hot summer, cool autumn and cold winter, and people are no exception. Therefore, the wisdom of health preservation is ultimately inseparable from the balance of yin and yang. "Yi copula" says that "flexibility can't last four seasons". This sentence means that everything in the world can't be changed without the law of yin and yang in the four seasons. The balance of yin and yang determines the life and death of everything. The law of human life should be to let nature take its course, and there will be ups and downs when nature takes its course. Neijing says that "four seasons win, spring wins long summer, long summer wins winter, winter wins summer, summer wins autumn, and autumn wins spring, so-called four seasons win". This means that the four seasons of a year are interrelated. For example, spring wins long summer, long summer wins winter, winter wins summer, summer wins autumn, and autumn wins spring. A season has seasonal climate constraints. This is the so-called constant victory in four seasons.

Hatha yoga is a compound word, where "ha" refers to the sun and "he" refers to the moon. "Hatha" means unity, or the balance of duality. Yoga postures come from hatha yoga: also known as Sun Moon Yoga or Yin Yang Yoga. It emphasizes physical exercise, breathing control, leading an honest and clean life, healthy diet and life rules. It is a popular yoga school in the world at present. The essence of his practice is that there is stillness in movement, stillness in movement, stillness in movement, yin in movement, yang in movement, both rigidity and softness, and yin and yang complement each other, thus playing the role of dredging qi and blood and stretching meridians. Hatha yoga believes that the human body includes two systems: the mind and the body. Most of people's ordinary ideological activities are disorderly and disordered, which is a waste of people's essence and spirit, manifested as useless consumption such as fatigue, excitement, sadness and excitement, and only a small part is used to maintain life activities, which is a common phenomenon of yin-yang imbalance. Usually, if this imbalance is not serious, it will naturally restore balance through rest; However, if self-discipline and adjustment are not active, this obstacle will become more and more serious, leading to mental or physical patients. Hatha yoga is to open the meridians through postures, pranayama, binding, fitting and cleaning exercises, so that energy (qi and blood) can circulate smoothly in the body. According to records, there are more than 84,000 kinds of yoga postures (according to historical records, the so-called 84,000 means a lot), but now there are not so many. When practicing posture, if we can use it correctly and arrange the posture order reasonably, we can get through all the meridians of the body. In yoga, posture is only a part of it. The ultimate goal of posture practice is to keep your body, head and neck in a normal physiological curve, so that your body and mind are quiet, and your breathing and heartbeat are stable.
