This tale of hidden treasure, a twin trained to kill his brother, and a young wushu warrior in the Valley of Villains is considered among the best from director Chu Yuan and celebrated author Ku Lung. Making the production even more special is the presence of international favorite Alexander Fu Sheng, as a kung-fu kid out to discover the truth about his parents' death.
