Tai chi

Tai chi is a Chinese martial art. Initially developed for combat and self-defense, for most practitioners it has evolved into a sport and form of exercise. As an exercise, tai chi is performed as gentle, low-impact movement in which practitioners perform a series of deliberate, flowing motions while focusing on deep, slow breaths. Often described as "meditation in motion," tai chi aims to cultivate and balance the body’s qi (vital energy), thereby promoting both mental and physical well-being.

Many forms of tai chi are practiced, both traditional and modern. While the precise origins are not known, the earliest documented practice is from Chen Village and Zhabao Village in Henan on the North China Plain, a region where centuries of rebellions, invasions, and adverse economic and social conditions nurtured the development of a wide range of martial arts, including those of the Shaolin Monastery on Mount Song at the western edge of the plain.

Most modern styles trace their development to five traditional schools: Chen, Yang, Wu (Hao), Wu, and Sun. In the early 20th century Yang Chengfu, Wu Jianquan, Sun Lutang, and others promoted and standardized the art for its health benefits in programs supported by the Nationalist government, an approach that was further expanded and institutionalized by the PRC government after 1949. In 2020, tai chi was included in the UNESCO List of Intangible Cultural Heritage of Humanity.

The name "tai chi", the most common English spelling, is not a standard romanization of the Chinese name for the art (simplified Chinese: 太极拳; traditional Chinese: 太極拳; lit. 'Taiji boxing'). The Chinese name was first commonly written in English using the Wade–Giles system as "tʻai chi chʻüan". But English speakers abbreviated it to "tʻai chi" and dropped the mark of aspiration. Since the late twentieth century, pinyin has been officially adopted in China and replaced Wade–Giles as the most popular system for romanizing Chinese. In pinyin, tai chi is spelled tàijíquán. In English, tai chi is sometimes referred to as "shadowboxing".

The etymology of tai chi's Chinese name is somewhat uncertain because of the lack of a record of spoken usage. Before the mid-nineteenth century, it appears that outsiders generically described the art as zhanquan (沾拳; "touch boxing"), "Long Boxing"(長拳), mianquan ("Soft/Cotton/Neutralizing Boxing"; 軟/棉/化拳)^{[citation needed]} or shisan shi (十三式; "the thirteen techniques"). In the mid-nineteenth century, the art began to be associated with the philosophy of taiji (see Conceptual background). This association may have originated in the writings of the founders of Wu (Hao)-style tai chi, perhaps inspired by a tai chi classic attributed to the semi-mythical Wang Zongyue that begins with the words "Taiji is born from Wuji; it is the mother of Yin and Yang". However, as the Wu (Hao) founders had no financial need to promote their art, their contributions to the "tai chi classics" were not distributed widely for many years. The first public association between taiji and the art was a poem by Imperial Court scholar Weng Tonghe describing a tai chi performance by Yang Luchan. It is not clear whether Weng was making a new connection or whether the new name was already in use. Written evidence for the Yang family's adoption of the name taiji first appeared in a later text, possibly completed in 1875 by Yang Luchan's son, Yang Banhou, or no later than the first decade of the twentieth century by one or more of Yang Banhou's disciples. By the second decade of the twentieth century, Yang Chengfu's disciples and Sun Lutang were using the term taijiquan in their publications, including in the titles of some of the tai chi classics. It then appeared in a book by a Chen family member, Chen Xin, published after he died in 1929.

Chinese philosophy, particularly Taoist and Confucian thought, forms the conceptual background to tai chi. Early tai chi texts include embedded quotations from early Chinese classics like the I Ching, Great Learning, Book of Documents, Records of the Grand Historian, and Zhuangzi, as well as from famous Chinese thinkers like Zhu Xi, Zhou Dunyi, and Mencius.

Early tai chi sources are grounded in Taiji cosmology. Taiji cosmology appears in both Taoist and Confucian philosophy, where it represents the single source or mother of yin and yang (represented by the taijitu symbol ). Tai chi also draws on Chinese theories of the body, particularly Taoist neidan (internal alchemy) teachings on qi (vital energy) and on the three dantian. Cheng Man-ch'ing emphasizes the Taoist background of tai chi and states that it "enables us to reach the stage of undifferentiated pure yang, which is exactly the same as Laozi's 'concentrating the qi and developing softness'".

As such, tai chi considers itself an "internal" (neijia) martial art focused on developing qi. In China, tai chi is categorized under the Wudang group of Chinese martial arts—that is, arts applied with internal power. Although the term Wudang suggests these arts originated in the Wudang Mountains, it is used only to distinguish the skills, theories, and applications of neijia from those of the Shaolin grouping, or waijia (hard/external styles).
