Hong Kong professor’s son testifies arguments between his parents were common before his mother’s killing, though his father was ‘never’ violent

A University of Hong Kong professor on trial for murder had often argued with his wife before he killed her two years ago, their son testified in court on Wednesday.

But Scot Cheung, 28, also observed that it was his mother, Tina Chan Wai-man, 53, who usually initiated the arguments, even criticising his father Cheung Kie-chung, 56, in public and in the company of others, such as during meals with relatives.
