[1][2] Prior to his election as councillor, Jang served as a professor of psychiatry at the University of British Columbia, a position he returned to after leaving politics.
[4] After graduating from high school, he worked on improving his grades at Vancouver Community College and then later transferred to Simon Fraser University where he went to complete his Bachelor's and Master's degrees in Psychology.
[4] He earned his Ph.D. in Personality Psychology[6] at the University of Western Ontario,[4] where he initially studied under the highly controversial Canadian psychologist J. Philippe Rushton, who was known for his research on race, intelligence and penis length.
In June 2014, Jang faced a court petition to remove him and fellow councilor Geoff Meggs from office for allegedly violating rules on conflict of interest in connection with the rezoning of a public housing project.
[14] In October 2016, Jang came under fire from Chinese Canadians after participating in the raising of a People's Republic of China national flag on the grounds of the Vancouver City Hall, sporting a red scarf.
The event, organized by the Canadian Alliance of Chinese Associations to mark China's National Day, is one of many flag ceremonies held at city hall.
The Alliance of the Guard of Canadian Values, a group of mainland Chinese immigrants which has protested local celebrations of Communist leader Mao Zedong, started an online petition calling for Jang's resignation.
