Great pictures.
Joey Wong doesn't play anyone but her character uses Jade Maiden Swordplay. And since her relationship with Huang Yaoshi never blossomed I assumed she was the movie's take on Lin Chaoying.
Brigette Lin was a filler character and Maggie Cheung was more or less, Yip Man Wing Chun, who has nothing to do with novel at all.
Hey, do you know the title of theme that was playing when Ouyang Feng learned 9Yin?
