Cheung competed in Sanya , China for the Miss World 2007 pageant in December 2007 . In the pageant she made history by becoming the first Miss Hong Kong to win the Beauty With A Purpose award , based on her charity work for the " Wai Yin Association " , a charitable organisation set up by a group of former Miss Hong Kong winners/participants since 1982 . Cheung tied with Miss Ecuador , Valeska Saab for the award , so both advanced to the semifinals automatically . She is the first Miss Hong Kong to make the semi-finals since Pauline Yeung in 1987 . The Miss World 2007 title went to Zhang Zilin of the People 's Republic of China
