Anyway, this is one of the establishing shots that confirms we are indeed in Hong Kong. The shot is along Chater Road looking at the old Hong Kong Club (and what looks like the old annexe building sticking out behind it).
There are a couple of pointers as to why this is flipped, the most obvious is then reversed writing on the vehicle on the far right. But look behind and you can also see the City Hall building in the gaps between the vehicles. Here's how it should look in reality.
According to Gwulo, the Hong Kong Club annexe was knocked down circa 1966. I'd be very surprised if this wasn't stock footage though and not shot specifically for this film at the time. I need to confirm the shooting dates but I was under the impression the film was late 1966.
