A Taiwanese originally named Chiu Kang-sang, Chiang was a martial arts opera performer in the troupe while he was in the army, and became a stunt actor in the film industry afterwards. When director Chang Cheh founded his own production company in 1974, he went to Taiwan looking for talent, and invited Chiang to come to Hong Kong. He joined Shaw Brothers in 1976 as a basic actor, and got his prominent role in Chang's Shaolin Temple that same year. His first leading role arrived two years later in The Five Venoms.
His filmography is filled with Chang Cheh's works, including Crippled Avengers, Invincible Shaolin, The Daredevils, The Rebel Intruders, Two Champions of Shaolin, The Flag of Iron, Legend of the Fox, The Sword Stained With Royal Blood, and House of Traps. Together with Kuo Chue (now known as Philip Kwok), Sun Chien, Lu Feng and Chen Tien-chi and a number of Taiwanese actors, Chiang became the new breed of "Chang's Cohorts." Chiang also went behind the camera and tried out as Chang's assistant director, as well as martial arts choreographer in various films. In 1981, with the support of Chang, he went back to Taiwan and founded a new production company with his Taiwanese cohorts. Chiang acted and choreographed the action scenes in their debut film, Ruthless Tactics.
