[Kingston Street, Causeway Bay, 2022]
The street signs in Hong Kong — as compact as they tend to be in size — subtly pack a lot of useful information.
Take this one in the picture. The straight edge on the left of the sign tells us that there is no more building further down the left, indicating that the street begins right there.
Meanwhile, the pointy edge on the right says there are more buildings or dwellings toward that direction. More specifically, #9 to #11, as printed on the sign as well.
One could then speculate that the opposite side of the street (where I was standing at the time) houses the even-numbered premises. That is exactly the case here.
