China's traditional film "Chivalrous Man".

This film is four episodes, and its name is Assassin. But I can't seem to find this film online. I'll tell you another story: the one who can see the butterfly is an old man, and the daughter that the bad guy with the big handprint uses to cover up his identity is actually the biological daughter of the good old man. The whole plot revolves around protection and assassination (kill who? Cai E? Forgot)
