香港小姐競選
Cheung was 21 when she competed Miss Chinese Chicago and is the only Chicago representative to ever hold the title. She was the winner of Friendship Ambassador as well. Cheung represented Hong Kong, China at Miss World 2012 in Ordos, Inner Mongolia, marking the first time a Miss Chinese International titleholder represents Hong Kong at Miss World instead of a Miss Hong Kong Pageant titleholder. This was due to the Miss World pageant timeframe shifting from November to August and thus conflicting with that of Miss Hong Kong Pageant. At Miss World Pageant 2012, Cheung entered top 47 in Top Model and Top 40 in Beach Fashion.
