Kung Fu Hustle Question
Ok, within the film Kung Fu Hustle at one point the criminal organisation The Axe Gang hires two assassins whom disguise themselves as Harpists (their also something of a homage to the blues brothers). However, they use a Chinese instrument known as a Guquin. For some reason alot of people who see this film state that it isn't a true Guquin, but something of a hybrid of a Guzheng and a Guquin.
My question is this. What is the discerning factor that makes this noticeable. IE : Why isn't the instrument a Guquin ? Is it something trivial (One string too many ?) or a big noticeable difference (Different shape, missing all of the 'guts' etc) ?
The scene in question (and some close ups of said Guquin/Guzhen) are in the you tube video below.
