Mr William Tsang Wai-sum started out his career in the early 1980s as an English copywriter at Reader's Digest, the company where he subsequently took up marketing responsibilities for the Asian region. The decade long association with Reader's Digest - then one of the biggest global publishers - has given Mr Tsang extensive experience in copywriting, publishing, and direct marketing.

During this period, he also did part-time English teaching at the School of Continuing Studies of The Chinese University of Hong Kong, the Hong Kong Management Association, and the Mechanical Engineering Department of PolyU. For his experience in copywriting, Mr Tsang was often approached by companies such as The Hong Kong Jockey Club, The Hong Kong Management Association, International Gold Coins, Reader's Digest, St Honore, and Universal Music to take up creative writing projects.
Mr Tsang joined HKCC of CPCE in 2004 as a full-time lecturer for English subjects.
