There were many rumours regarding the cause of her death. Some had attributed it to an accident, suicide or perhaps even foul play. One of the most widely circulated rumours was that her suicide was the result of her depression over her supposed broken relationship with then-TVB actor, Kent Tong Chun-yip. (In an interview conducted by a Hong Kong radio station on 14 March 1985, when asked about rumours regarding her relationship with Kent Tong Chun-yip, Yung had explained that he was merely a friend and respected colleague.) The rumours concerning the association of her death with Kent Tong Chun-yip were largely based on Stephen Chow's account of her last 24 hours. There were also rumours which claimed that Stephen Chow was Yung's boyfriend. According to Yung's TVB colleagues, she behaved normally in the days before the suicide and did not appear depressed or suicidal. Yung sounded very optimistic about her future in her radio interviews both on 14 March 1985 and one conducted two weeks before her death.
