Deliberate mistake: When Betty is about to fight Master Tang he is holding the chain, but when the music starts he doesn't have it. (00:31:40)
Continuity mistake: When Betty is fighting Chosen One as a baby, she tries to stab Chosen One. Chosen One then grabs Betty's hand, and whilst he is kicking Betty, you don't see his hand holding Betty anymore. (00:03:15)
Continuity mistake: Sometimes the back of the Chosen One is shown, and you can tell it's the guy from the last movie.
Answer: Nothing - that section of the movie was taken from the original "Tiger and Crane Fists," and so was never English to begin with.
