Often shortened to t'ai chi, taiji or tai chi in English usage, t'ai chi ch'uan or tàijíquán is an internal Chinese martial art practiced for both its defense training and its health benefits. Though originally conceived as a martial art, it is also typically practiced for a variety of other personal reasons: competitive wrestling in the format of pushing hands (tui shou), demonstration competitions, and achieving greater longevity. As a result, a multitude of training forms exist, both traditional and modern, which correspond to those aims with differing emphasis. Some training forms of t'ai chi ch'uan are especially known for being practiced with relatively slow movements.
Today, t'ai chi ch'uan has spread worldwide. Most modern styles of t'ai chi ch'uan trace their development to at least one of the five traditional schools: Chen, Yang, Wu, Wu (Hao), and Sun. All of the former, in turn, trace their historical origins to Chen Village.
The term "t'ai chi ch'uan" translates as "supreme ultimate fist", "grand supreme fist", "boundless fist", "supreme ultimate boxing" or "great extremes boxing". The chi in this instance is the Wade–Giles transliteration of the Pinyin jí, and is distinct from qì (ch'i, "life energy"). The concept of the taiji ("supreme ultimate"), in contrast with wuji ("without ultimate"), appears in both Taoist and Confucian Chinese philosophy, where it represents the fusion or mother of yin and yang into a single ultimate, represented by the taijitu symbol . T'ai chi ch'uan theory and practice evolved in agreement with many Chinese philosophical principles, including those of Taoism and Confucianism.
The Chen family-style (陳家、陳氏 or 陳式 太極拳) is the oldest and parent form of the five traditional family styles. Chen-style is characterized by Silk reeling (chán sī jìn; 纏絲勁), alternating fast/slow motion and bursts of power (fa jin; 發勁).
Contemporary t'ai chi ch'uan is typically practised for a number of widely varying reasons: health, external/internal martial art skills, aesthetics, meditation or as an athletic/competition sport (sometimes called "wushu tai chi"). Therefore, a teacher's system, practice and choice of training routines usually emphasizes one of these characteristics during training. The five traditional schools, precisely because they are traditional, attempt to retain the martial applicability of their teaching methods. Some argue that the Chen tradition emphasizes this martial efficacy to a greater extent.
The origin and nature of what is now known as tai chi is not historically verifiable until around the 17th century. Documents of this period indicate the Chen clan settled in Chenjiagou (Chen Village, 陳家溝), Henan province, in the 13th century and reveal the defining contribution of Chen Wangting (陈王庭; 1580–1660). It is therefore not clear how the Chen family actually came to practise their unique martial style and contradictory "histories" abound. What is known is that the other four contemporary traditional tai chi styles (Yang, Sun, Wu and Woo) trace their teachings back to Chen village in the early 1800s.
Sichuan (Chinese: 四川; pinyin: Sìchuān, formerly Szechwan or Szechuan) is a province in southwest China. The capital is Chengdu, a key economic centre of Western China.
The name of the province is an abbreviation of Sì Chuānlù (四川路), or "Four circuits of rivers", which is itself abbreviated from Chuānxiá Sìlù (川峡四路), or "Four circuits of rivers and gorges", named after the division of the existing circuit into four during the Northern Song dynasty.
Throughout its prehistory and early history, the region and its vicinity in the Yangtze region was the cradle of unique local civilizations which can be dated back to at least the 15th century BC and coinciding with the later years of the Shang and Zhou dynasties in North China. Sichuan was referred to in ancient Chinese sources as Ba-Shu (巴蜀), an abbreviation of the kingdoms of Ba and Shu which existed within the Sichuan Basin. Ba included Chongqing and the land in eastern Sichuan along the Yangtze and some tributary streams, while Shu included today's Chengdu, its surrounding plain and adjacent territories in western Sichuan.
