In the late 1980s, Mr Tsang migrated to Canada where he pursued a marketing career in the business sector for about 10 years - first as Supervisor of Sales and Marketing Analysis (North America) of a Canadian publisher, then as Asia Marketing Manager of a US-based multinational ocean liner shipping company, and subsequently as Marketing Director of a Hong Kong publicly-listed airfreight logistics company.
In addition to his business background, Mr Tsang has extensive experience in language-related works. He has held the position of translation manager of a local financial printer, and the position of book editor of the Commercial Press and the Chinese University Press. His language teaching career began with the School of Continuing Studies of the University of Toronto as a part-time instructor. Since then, he has served as a full-time lecturer at a local post-secondary institution, a part-time lecturer at Lingnan University, and a part-time course developer and course coordinator at the Open University of Hong Kong.
A two-time winner (1st prize and 2nd prize) of the Hong Kong Youth Literature Award in literary criticism, Mr Tsang has authored three textbooks on translation for the Bachelor of Arts (Honours) degree programme of the Open University of Hong Kong. He has also translated and published several books and articles, including A Work in Progress and Macau 2020 - the Long-term Objectives and Development Strategies in 20 Years.
