Although the roots of qigong can be traced back millennia, qigong as a development of post-Mao China, contending that with the end of the Cultural Revolution came an implicit admission in China that Marxist ideology was useless, and that the 'totalitarian state' wherein the party leader was 'god' was all but defunct. A spiritual crisis thus ensued. Because the 'big religions' were desecrated and banned during the Cultural Revolution, to many Chinese they no longer held the attraction they once did. Qigong is said to have evolved within this historical context, as a “spiritual, slightly mystical branch of Chinese medicine.” Ownby gives a similar account of the history of qigong in China. Qigong was promoted in post-Mao China for both practical and ideological reasons, and in this period it took on "unprecedented importance. On a practical level, it was hoped that qigong would improve the general health of the populace and thus curtail government healthcare expenditure. Ideologically, Ownby contends that many within the Communist government were 'quite taken' with the idea of qigong being a specifically 'Chinese science', a part of the PRC's "new nationalism, a frequently chauvinistic claim to cultural greatness and superpower status. Qigong was not considered religious either by the authorities or by qigong practitioners, which immensely helped its growth. Eventually the state-administered China Qigong Scientific Research Association was formed, supposed to register qigong groups and conduct 'scientific' research. By the time the association was established, there were already 2000 qigong organizations and between 60 and 200 million practitioners across China.
Qigong quickly became a social phenomenon of 'considerable importance'; the topic was also explored by novelists and journalists, and qigong newspapers and magazines appeared in abundance to cater for the public's interest in the subject. The original small-group, master-disciple pattern was transformed into a mass experience, with qigong 'masters' organising 'mass rallies' to demonstrate to paying customers a range of qigong specific phenomena such as trance, possession, and a variety of otherworldly states. Qigong was practised widely in public parks and on university campuses. Demographics included both the 'old and suffering' as well as the 'young and curious'. Ownby suggests that the profile of qigong practitioners during this period fit that of the Chinese population in general, “men and women, rich and poor, educated and uneducated, powerful and powerless, urban and rural, Party and non-Party.
Johnson writes that the early 1990s saw a 'qigong craze', with qigong being a widely accepted part of society. Qigong was able to adapt itself to a scientific discourse, which allowed it to survive the suspicions of the atheist state. It was heralded as a form of physical therapy, to be supervised by doctors. Experiments were conducted which purported to show that qigong could cure chronic health problems. Claims that qigong could have some role in developing latent 'supernatural powers' also emerged, such as the ability to levitate, heal illness, telekinesis through emissions of qi, the ability to 'read via the ear', and a “host of other remarkable talents, many of which would fall under our category of extrasensory perception.
Johnson opines that the Party was to some degree still distrustful of qigong. Qigong remained a private exercise, as opposed to formal religions which center on temples, churches and mosques. These can be run by government officials and are ensured to remain loyal to the state. Johnson's analysis here coincides with that of Chan. While qigong is focused inwardly, outside the state's control, it is performed publicly in groups: “To a government that is used to controlling all aspects of public life, this is perplexing: qigong practitioners are in public and doing something en masse, so by rights they should be formed in an organisation and this organisation should in some way be run by the government. But what they are doing together is meditating, an inner discipline that the party can't monitor. Ownby suspects that qigong's ostensible autonomy from the state is in fact partly what contributed to its great popularity. Johnson writes that the 1990s saw an 'uneasy standoff'; the 'Three Nos' policy was adopted: No Promoting, No Criticizing, No Debating.
Ownby comments that the emergence of qigong coincided at a historic moment where technology and means of communication—such as books, tapes, television and Internet—were greatly advanced, allowing such groups to become aware of their size and geographical reach. Ownby suggests that this is a paradoxical situation of a deeply rooted Chinese tradition now adapting to a modern setting.
Today millions of people in China and around the world regularly practice qigong as a health maintenance exercise. Qigong and related disciplines are still associated with the martial arts and meditation routines practiced by Taoist and Buddhist monks, professional martial artists, and their students. Once more closely guarded, in the modern era such practices have become widely available to the general public both in China and around the world.
Medical qigong treatment has been officially recognized as a standard medical technique in Chinese hospitals since 1989. It has been included in the curriculum of major universities in China. After years of debate, the Chinese government decided to officially manage qigong through government regulation in 1996 and has also listed qigong as part of their National Health Plan.
Qigong can help practitioners to learn diaphragmatic breathing, which can be helpful in combatting stress. In contrast, Taoist qigong employs the inverse breath of inhaling to the back of the thoracic cavity rather than diaphragmatic breathing.
Yan Xin (嚴新), a doctor of both Western and Chinese medicine as well as founder of the relatively popular Yan Xin Qigong school, suggests that in order for qigong to be accepted by the modern world it must pass the test of scientific study. Without such studies, Yan maintains, qigong will be dismissed as "superstition" (see "Criticism of Qigong" chapter below). In the mid-1980s he and others began systematic study of qigong in some research institutions in China and the United States, more than 20 papers have been published.
While uncertainty persists regarding the spiritual aspects of qigong, Qigong may also be seen as a socially conducive warm-up to the day. Many practitioners choose the early morning to practice qigong and find it an easy way to stretch and warm up the metabolism
