The solo, or group solo practice of T'ai Chi has become a popular form of exercise the world over. Just in China millions of people practice some form of the traditional art known in Mandarin (太極拳) Chinese as "Taijiquan / Tàijíquán". The so called Wade-Giles "romanized" transliteration, more appropriate for English speakers, is "T'ai Chi Ch'uan", — what in the popular vernacular has become more simply "Tai Chi".

Yolo County has a relatively long history of T'ai Chi Ch'uan. In the early 1970's the famous San Francisco T'ai Chi Ch'uan Master Choy Kam-Man used to travel to Davis on a regular basis to teach classes on the University of California campus. To this day there are still practitioners in Davis, some who are now teaching, who were Master Choy's students in those times.

Master Choy was a very traditional strictly Yang Family Style, T'ai Chi Ch'uan instructor. His father, Choy Hok-P'eng, sometimes referred to as "The Elder Master Choy", was a direct lineage disciple of Grandmaster Yang Cheng-Fu, who popularized the traditional Yang Family solo Long Forms Set which we know today. Master Choy Hok-P'eng came to the United States in 1939, specifically to teach T'ai Chi Ch'uan to the San Francisco - China Trading company families, just three years after Grandmaster Yang had passed away. Thus The Elder Master Choy is sometimes referred to as the "Father of T'ai Chi" in the Americas.

To Woodland, T'ai Chi Ch'uan came later, in the 1980's, also as Yang Style but through a different "Lineage", via students of students of Master Cheng Man-Ch'ing, who came to the United States in 1964, and who also had been a disciple of Grandmaster Yang Cheng-Fu (see also T'ai Chi Ch'uan History in Woodland.

Currently in Woodland YCSifu teaches traditional Yang Style T'ai Chi Ch'uan. YCSifu was a direct student of Master Choy Kam-Man, his first teacher, as well as later also a student of various students in the Master Cheng Lineage (see YCSifu for details).

Some distinction needs to be made between what most Americans regard as Tai Chi, — a meditative movement activity done for relaxation, wellness and health, often done by older people, versus the more traditional T'ai Chi Ch'uan (Taijiquan) which can include various martial practices, usually including two person interactive, Martial play practices (such as T'ui Shou 推手 (TuīShǒu) "pushing hands", or San Shou "free hands" Forms or sparring), and possibly also including the use of implements — a staff/pole (Kun 棍 (Gùn), rattan or waxwood), and/or broadsword/sabre (Tao 刀 (Dāo)) and/or straight sword (Gien 劍 (Jiàn), usually hardwood, or actual 'live' metal).

The practice of T'ai Chi, as a non-violent martial art indeed worthy of a violent situation (id est T'ai Chi Ch'uan), or at whatever level, can present an opportunity for numerous benefits to the practitioner, for health and well being (MayoClinic-StressManagement, NCCAM-ResearchSpotlight), as well as ultimate self-defense (
