All I can say is...wow! ANd how did you notice that...and as long as the bustier was the right way around, doesn't matter, cuz that's where I was looking!
And perhaps the Martial Arts crew where Japanese, and didn't know chinese. They also flip certain scenes, so maybe they did that?
If you can post a picture, I know someone who is CHinese, and I can get her to look at it if you like.
