Help finding old kung fu film.

Years ago I was flipping thru the channels and stopped on a kung fu type movie. It had a boy and girl hiding in a cabin or shack and these horsemen came up. The boy went outside which he was then overtaken and hung upside down by his feet. The horsemen took turns riding by him hitting him with torches on his back and chest. Then I assume the leader comes up and cuts the bottom of the boys feet with a dagger. They leave and he proclaims his revenge. Then another scene had this younger woman fighting someone as they were flying thru the air crouching tiger hidden dragon style. The movie may have been in black and white. I know that’s not much to go on but id like to see,have the whole movie. Any help is greatly appreciated. Thanks.
