Yellowthread Street (TV Series) - Bruce Payne (1990) - Kui In Fong, Sheung Wan

Just before we see the fight that gets started on Sai Street, we see Brady (played by a very wooden Mark McGann) driving a car down a road pretending to be a buyer but really just trying to see what the girl owner is up to (selling drugs in case you didn't know).

Like in the show, this road is the one that leads down to Sai Street, so when we catch a passing glimpse of the fight that is erupting there between Bruce Payne and the triads, it's not a bad approximation of what you would see in reality - although the place has undergone a huge amount of redevelopment since Yellowthread Street was filmed in the late 1980's (it was shown in the UK in 1990...I think?). The fenced area on the right of the screen grabs is Blake Garden. Here's the modern streetview.
