I had to edit the unimportant stuff to make it less than 10 min. I also got some cool info from tsinoy147 and his video. it is shown below (Note: This video is not mine.)
Ripped from the DVD of Kung Fu Hustle
Kung Fu Hustle is a humorous parody and a special tribute to the wuxia genre, played and directed by Stephen Chow.
The Harpists are a pair of hitmen dressed in long grey robes, sunglasses and broad rimmed hats; who where hired by the Axe Gang to rid of Coolie, Donut, and Tailor. They are highly knowledgable about their opponents and knew who they were and their fighting styles before the Axe gang hired them, though they where quite suprised to find the Lions Roar actually existed.
Their weapon of choice is an (immensely over-sized) Gu qin-Guzheng hybrid. Although capable of melee combat, they much prefer to use their special fighting style, Deadly Melody. They can use their qi to focus and mold the sound waves produced by the instrument into a range of deadly forms, ranging from scimitars, to fists and even a small legion of sword-wielding undead in ancient Chinese armor. The ability is not purely offensive; it can be used to form a protective "wall" that actively blocks and forcibly repels incoming weapons. With practically every string they play from their musical instrument, killer objects, usually almost invisible, would fly from it, aiming for the unfortunate target.
The first harpist appears to be the older of the two. He fights Tailor in his shop and proves to be capable of matching him in hand to hand combat (though he did have the element of suprise on his side). He primarily uses his long fingernails as claws when fighting, and is capable to cutting through plaster with relitive ease. He uses the Guqin as a back up, though allows his partner to do most of the firing. Despite his hand to hand combat skill he proves to be no match for the landlord.
The second harpist appears younger and appears to be blind, since in an earlier scene the first harpist had to assist him to his drink and frequently cocks his head to focus on particular sounds. Despite this handicap, he seems to have excellent accuracy and skill with the Gu qin at long range, and was able to tell where his opponents where even after dodging. His main offense is the Gu qin which he plays a deadly melody; his secondary defense is punching.
They are defeated by Landlord, who was between them; their attacks merely were deflected by him and onto each other. Then they are decimated by the Landlady with her Lion's Roar.
