While studying for a career in the tourism industry at the Université du Québec à Montréal (UQAM), she entered and won the Miss Chinese Montreal contest in 1992. She then went to Hong Kong, in her first trip away from home, to participate in the Miss Chinese International Pageant 1993, in which she won despite not knowing a single Chinese word. This opened doors for her to launch her acting career there, despite not speaking a word of Cantonese at the time, and despite her extremely limited acting experience (an uncredited ten-second non-speaking role as a gum-chewing prostitute in Denys Arcand's Love and Human Remains). She had to choose between acting in Hong Kong and becoming the weather-forecast presenter at Société Radio-Canada, the French-language government television network in Canada.
Chung married Glen Ross in 1998, and gave birth to their daughter Yasmine in Montreal in the middle of the 1998 Ice Storm. Chung and Ross divorced in 2002, and Chung has sole custody of Yasmine.
In 2003, Chung married music Producer Jon Yen. They have two daughters, Jaden Chloe, born in August 2008, and Cayla Janie, born in February 2010. Chung and Yen divorced in 2011.
In November 2016, Chung married actor Lunshuo Zhang.
