T'ai chi ch'uan (simplified Chinese: ???; traditional Chinese: ???; pinyin: t鄆j韖u醤; Wade-Giles: t'ai chi ch'黙n; literally 'Supreme Ultimate Fist'); often shortened to t'ai chi or tai chi in English usage; is a type of internal Chinese martial art practiced for both its defense training and its health benefits. It is also typically practiced for a variety of other personal reasons: its hard and soft martial art technique; demonstration competitions; and longevity. As a result; a multitude of training forms exist; both traditional and modern; which correspond to those aims. Some of t'ai chi ch'uan's training forms are especially known for being practiced at what most people categorize as slow movement.

Chengdu; known formerly as Chengtu; is the capital of Sichuan province in Southwest China. In the early 4th century BC; the 9th Kaiming king of the ancient Shu moved his capital to the city's current location from today's nearby Pixian.
