Cho studied in San Francisco, United States. She came back from her studies in 2003 and competed in the 2003 Miss Hong Kong Pageant. A favorite at the start of the competition, she made it into the semifinals and won the Perfect Team Award. Then in August, she competed in the finals and beat favorites like Selena Li, Rabee'a Yeung, and Carrie Lee for the title. Later Cho appeared in TVB series including Split Second, Guts of Man, and The Charm Beneath. She also became the seventh contestant from Hong Kong to win the Miss Chinese International First Runner Up title. Cho is also the second woman after Winnie Yeung (also from Hong Kong) to win the Miss Friendship title. The eventual winner of the 2004 Miss Chinese International title was Linda Chung.

In 2006, Cho completed her studies at GIA (Gemological Institute of America) in New York City and is now a Graduate Gemologist. She returned to Hong Kong in September 2006. Though she claimed she was working as a PR at a jewelry company when she first returned to Hong Kong, she is now working as an actress once more.
