As a young man, he studied t'ai chi ch'uan, along with his brother, under the supervision of Yang Shao-hou. There was a tradition in the Chinese martial arts that youngsters be taught by teachers of a generation older than their parents'. Since Wu Ch'uan-yü had died the same year Wu Kung-tsao was born, he and his brother were taught by Yang Shao-hou, who was technically a generation senior to their father. Both Yang Shao-hou and Wu Chien-ch'üan were famous for their "small circle" martial expertise. The motions of t'ai chi ch'uan forms and pushing hands are all based on different sized circles, small circle movements in the forms and applications follow a more compact pathway for different leverage applications than larger circles. In the 1920s Wu Kung-tsao served first as an infantry officer in the Thirteenth Brigade of the Nationalist army until 1929, then later as a martial art instructor for the HunanMartial ArtsTraining Centre as well as an instructor for the famous Ching Wu martial art school. During the 1930s, he wrote a well-known commentary on the classic writings in 40 chapters on t'ai chi ch'uan that his grandfather had inherited from Yang Pan-hou. His commentary was published as Wu Chia T'ai Chi Ch'uan, also known by English speakers as The Gold Book because of the colour of its cover. In 1937, he established his family's first school in Hong Kong. In addition to his teaching and literary contributions to the art, Wu Kung-tsao became known as a specialist in the nei kung aspect of T'ai Chi training, both for martial purposes and for therapeutic interventions along the lines of traditional Chinese medicine. Wu Kung-tsao stayed on the mainland after the ChineseCommunist takeover in 1949. During and for a short time after the Cultural Revolution of 1964-1978 he was imprisoned by the Red Guards due to his history as a Nationalistmilitary officer, a traditional Confucianscholar and Taoist teacher as well as a hostage to ensure the "good behaviour" of the rest of his family who were at the time living in Shanghai and Hong Kong. He was routinely tortured while a prisoner but was finally released in 1979, when he moved again to Hong Kong. Wu Kung-tsao's second son Wu Ta-hsin was also known as an expert martial artist and teacher who in his turn was the senior instructor of the Wu family schools internationally from 2001 until 2005.
