It should be noted that a Chinese vampire is more like a zombie than a western vampire. 救殭清道夫 (Vampire Cleanup Department) (Blu-ray release 2017-6-23) tells the story of a secret government department in Hong Kong that deals with the vampires. The protagonist got bitten by a vampire but is not harmed – this makes him a natural fit for the department. We see him going through a bit of training, but a lot of time is spent on his romance with a female vampire, who happens to be very pretty.
Since she cannot talk, the movie compensates for this by giving her a smartphone with a Siri-like function. The way it works makes even less sense than her evil former self transforming to be an adorable and cute love interest. This romance cannot be compared to the achievement in Twilight (2008), however. It is mostly a comedic relief only. The movie is not bad but nothing to write home about.
