Help finding Martial Art Movie Title

Hello,

I am in search of several martial art movies. One is an earlier Jet Li supernatural movie where the main bad guy used a scroll to become more powerful, but the price the scroll turned him into a woman.

The next movie is a Romeo and Juliet type movie where a Chinese clan and a Japanese clan makes their children marry and through out the movie the newlyweds test each other on who's style of martial arts is better. In the end they fall in love with each other, of course after beating the bad guys.

The Romeo and Juliet type martial art movie, I could swear that their was a sequel. In which the newlyweds have twins (of course their is strife between the newlyweds)and they teach them their styles. But while teaching them, the newlyweds, also teach their martial art style and they have to work together, in the end they triumph.

Can you help me with the titles of these martial art movies?
