Kim Newman in Anno Dracula (2011 [1991]) answers:

The Chinese movie tradition of the hopping vampire (jiang shi or geung si) is one of the odder strains of vampirism. I saw Ricky Lau’s Mr Vampire (1985) in London’s Chinatown before the film and its many spinoffs, sequels and variants had made much impact outside its home territory. A lingering aftereffect of this cycle is that, from Buffy and Blade on, even Western vampires tend to know kung fu.
