That news discussed in this thread long times ago. Not only ruby, so many other actresses in Hua Yi company did camera test because this movie is HY-USA company cooperation. After they decided the 2 actresses, HY's officials said they should casts the China actress for the cooperation rule(I don't know what is that). Ruby is taiwanese, and Fann from Singapore. I really think company just use Ruby and Fann's name to promote the movie.
LBB looks much awesome than other actress in that movie. Anyway, this movie isn't related ruby at all. Don't need to talk about this
they are China group singer BOBO..they visited taiwan, and meet ruby at taiwan.
