Super cool picture showing the origins of Sham Shui Po's wide roads, which were first water channels in the 1920s, then market places in the 80s, before they were turned into wide and noisy roads. Imagine your city’s avenues become permanent buzzing markets

I have memories of HK in the late 80s. It was super gritty. Stinky smells wafting in the humid air, sneezing into a tissue would reveal soot you breathed in, seas of people. It’s much cleaner now. And less people on the streets, despite an increase in population, I think that’s the impact of the Internet.
