Extremely enjoyable thread of photos, thanks for sharing them. Never knew HK had these "nullah" things in Yuen Long, even though I've visited Hong Kong 8 times. Probably because I live in Chai Wan. Awesome images!
Thanks! There aren't many nullahs on HK Island although there is one in Wong Chuk Hang. And of course that's where Stone Nullah Lane in Wan Chai gets it name from.
