Miss Hong Kong Pageant
She competed in Miss Hong Kong Pageant which was held on July 19, 2008 at the Hong Kong Convention and Exhibition Centre. She won the Miss Hong Kong 2008 pageant. After winning the crown, Cheung was criticized for smoking and kissing her boyfriend in public. The pageant organiser TVB froze Cheung's contract following criticism of her behaviour on public, which it deemed unfit for a Miss Hong Kong champion. Cheung was not invited to present at Miss Hong Kong Pageant 2009 and crown her successor, Sandy Lau.
