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 Hunan Martial Arts Training 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 (including the original 40 chapters) was published as Wu Chia T'ai Chi Ch'uan (吳家太極拳, Wu family 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 Chinese Communist 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 Nationalist military officer, a traditional Confucian scholar 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.
