HKMDb credits:
"Phillip Ko Fei ... Loan shark"
There's indeed a ?? in the credits, but I couldn't recognize Phillip Ko anywhere in the movie, neither in the US vhs nor in a Taiwan vhs copy.
Also, the only person that may point to a "loan shark" (this word is nowhere mentioned in the subtitles) is the guy in the Karaoke bar who offers Chan Wai-Man's girl money for keeping him company on some journey, and Chan Wai-Man urges her to agree, because he's after the money.
There are around 6 or 7 different ??'s in HKMDB, mostly without pictures.
