There is a woman in it who looks very similar to Gong Li. In it she's wearing a long flowy white dress (might be red) and has extremely long black hair during a scene where she is fighting with a sword while floating in the air. Sorry it's so vague, but that's all I remember and I know I used to love this movie.

What is the movie about that would help a lot too.

Similar fight scene Hero - Flying Snow vs Moon (https://www.youtube.com/watch?v=LDagtOmhkGo)

Ended up figuring it out. BLOOD the Last Vampire
