Hong Kong singer and actress Gillian Chung, half of the Hong Kong pop duo Twins, opened a match of the 2008 FIBA Diamond Ball for Women as a tournament ambassador in Haining, eastern China's Zhejiang Province, on Tuesday evening.

Web site hinews.cn reports that it is Chung's first appearance on the Chinese mainland after a nude photo scandal early this year.

Chung's agent said she attended the event for its positive cause, but it does not signal her return to the stage. Chung will formally resume work after the Olympics.
