Need help with name of movie

Only remember bits of the movie. If someone could help I would greatly appreciate it. Saw a kung-fu movie probably made in the 70's or early 80's. It had a female lead, she was going to jump off a bridge to commit suicide. She was stopped by a female passer by and convinced her to travel with her for a year then she could come back and jump. A year passed and they came back to the bridge, she jumps off and flies back up once she nears the water. Later in the movie she flies from tree to tree and uses a combination of two swords to cut out someone's heart. Does anyone know this movie. Thanks.
