Here are the original screen captures.
Now, the more eagle-eyed of you should have spotted something a bit awry. It's not obvious unless you are familiar with the way Chinese characters are written - you don't even have to know what the characters say, just be familiar with writing convention - but you should know that the Chinese shop sign in the upper cap is actually reversed. Here's what the location should actually look like.
I have no idea why the film was reversed. Now, if this was the 1970's then i could expect some inadvertent flipping due to the way the film is processed, like we saw in That Man Bolt. I have no idea what recording format was used for this film but I would say that digital movie would make this kind of error less likely. Anyway, the sign - when read the correct way - give us a shop name: 寶泰珠寶金行 - a jewellery shop on Lok Shan Road next to where the earlier filming around Mei King Street. Here's the Streetview that shows the corner building in the shot was actually once painted blue. The junction with the blue building is the junction with To Kwa Wan Road.
