What is the origin of the word "paparazzi"?

Paparazzi first appeared in 1958. It was originally Italian "paparazzi", which is the plural of the Italian surname Paparazzo. Paparazzi was initiated by Hong Kong people. After paparazzi were introduced into Hong Kong, Hong Kong people renamed paparazzi Puppy. First, the pronunciation is similar, and second, the tracking behavior of such journalists is similar to that of dogs. Paparazzi, the word comes from the police department in Hong Kong, not the news unit, and it didn't mean reporters at first. Paparazzi is a team of CID (criminal police) department of Hong Kong police who specializes in tracking criminals or suspects. Because of its ingenious tracking method and perseverance, it became famous after being exposed by the media and made into a movie plot.
