Chiang commenced karate training in 1970 in the Flora Ho Sports Centre of the University of Hong Kong as a member of the first batch of trainees in that dojo. He had continued his practice there almost nonstop as a trainee and a coach till 2006.
Chiang’s karate training was under the auspices of the legendary Shihan Kai Takahashi. He was greatly indebted to many coaches, including Shidoin Yeung Chi Chung, Shihan Shair Wah Kwan and Shihan Cheung Shiu Kwong.
Chiang played an instrumental role in the development of karate as a sport in Hong Kong. He served as the Assistant Secretary of the Hong Kong Amateur Karatedo Association (founded in 1974 and the predecessor of the Karatedo Federation of Hong Kong, China Limited) in its beginning years and as the Vice-Chairman in the 1990s. He also provided advice and direct assistance to the Karatedo Federation in coping with the suspension of its membership in the Sports Federation & Olympic Committee of Hong Kong, China in 2018, culminating in its membership reinstatement in December 2021.
Chiang had participated in a number of local and overseas karate tournaments. Notably, he was the leader and referee of the Hong Kong team in the 1st Fukuoka World Women’s Cup – Karate, jointly organized by the World Union of Karatedo Organizations and the Japan Karatedo Federation in July 1990 in Fukuoka, Japan.
