Need help identifying someone

Long story short, my father (see photo) slipped and broke his arm while in Kowloon in 2001. We ended up being taken to a Chinese medicine doctor and herbalist (who knows where in the city), but in his office he had a photo of himself in the movie Bloodsport, yes the one with JCVD. We don’t speak Cantonese or Mandarin (we’re Vietnamese) but one of the witnesses to my dad’s accident (left of the photo), the one who brought us to the doctor, helped us with communication. On the right of the photo is the doctor and Bloodsport actor.
My father is now recounting his experience and we’re trying to figure out who this doctor is, his name, and if he still has his Chinese medicine practice. After researching the cast of Bloodsport, I am guessing is it Dennis Chiu??
Was wondering if anyone here happens to live in HK or better yet Kowloon. This is like finding a needle in a haystack! Thanks in advance for any leads!
