Qigong and Tai Ji Chuan are the same in many aspects, but there are also many differences. As the name implies, Tai Ji Chuan belongs to a kind of martial arts, and some people call it "flexible martial arts". The specific contents of Tai Ji Chuan's movements include basic skills, pushing hands, Sanshou and equipment routines besides boxing routines. As the content of Wushu, its main function lies in attack and defense. The similarities between Tai Ji Chuan and Qigong are as follows: First, with the development of society, Tai Ji Chuan, as one of the martial arts schools, gradually reduced the role of fighting and attacking in social life, and highlighted the fitness value and traditional artistic performance value of Tai Ji Chuan. The famous taiji chuan master has the viewpoint of "explaining the intention in detail in order to prolong life and not return to spring" in "Songs of Thirteen Potential Performances". Therefore, as far as the fitness function of Tai Ji Chuan is concerned, it has something in common with Qigong. Secondly, as far as the emergence of Tai Ji Chuan is concerned, it not only absorbed the advantages of many martial arts boxing methods, but also absorbed the essence of ancient health preservation techniques such as inducing vomiting, making some essentials and methods of Qigong exercise an important part of Tai Ji Chuan's basic skills. Thirdly, from the requirements of Qigong exercise, Tai Ji Chuan's exercise also pays attention to the guidance of thoughts, demanding calm and relaxation, as well as body adjustment, pranayama and pranayama. From this perspective, Tai Ji Chuan can also be listed as one of the qigong techniques. Fourthly, in theory, they are all guided by China's ancient theory of Yin and Yang, and use the meridian theory of traditional Chinese medicine to explain the phenomena in their practice. Although there are many similarities between Qigong and Tai Ji Chuan, they are different in many aspects because of their different ultimate goals of formation and development. First, from the point of view of formation and development, Tai Ji Chuan was born for the need of winning the battle on the battlefield, and gradually developed in the constant practice of fighting and attacking; Qigong is mainly formed and developed in medical practice to meet the needs of fitness and health preservation. Secondly, as far as the methods and essentials of exercise are concerned, qigong mainly achieves the purpose of fitness through physical relaxation and mental relaxation, and mental adjustment is its core content; Tai Ji Chuan, on the other hand, started with body movements, and through the process of "from loose to soft, from soft to hard", exercised a flexible, continuous and penetrating power of winding silk. Thirdly, as far as its ultimate purpose and function are concerned, Tai Ji Chuan finally achieved the perfect combination of intention, qi and force through the continuous practice of "drawing air with intention and drawing air with gravity", thus achieving the purpose of meaning qi and qi as force in martial arts; The ultimate goal of qigong is medical treatment, strengthening the body and prolonging life after practicing qigong. In a word, Qigong is similar to Tai Ji Chuan, but not exactly the same. Qigong has become an important part of Tai Ji Chuan's basic practice, and some methods and essentials of Tai Ji Chuan have also become the reference for people in Qigong field to create Taiji Qigong.
