Lately, I've noticed more information boards springing up around town.
They look like they're put up for tourists (check out the Japanese version) but they're also great for people who live here – like us – who are curious about the local history but don't know enough Cantonese to find out more.
Here's one about the watch tower in Chung Hau – turns out it's called Yu Tak Lei Yuen watchtower and was used to spot pirates coming up River Silver.
There are others scattered around the area but I haven't gotten round to taking photos of them yet. Will post more when I do.
