Last week we introduced the new Places feature. They help you find your way to a place in Hong Kong.

That's great if you know where you want to get to. But what if you've just got a vague idea? eg 'I expect to be working in Central, which serviced apartments are nearby?'. Or "I'm staying in a hotel on Nathan Road, any friendly pubs nearby?".

Join us on a walk around Hospital Hill in Wanchai, looking for signs of the air-raid tunnel network that was dug under this hill. The hill is currently the site of the Ruttonjee Hospital, but at the time of the second world war you’d have found the Royal Naval Hospital located here.

You probably know the stone steps of Pottinger Street in Central, but how did it get its name, and what happened to its tunnel?

Next time you’re on the MTR, how about learning Chinese characters from the route map? Ok, learning to read and write Chinese needs several years’ full-time study, but if you can spare a few minutes at least we can give you a good idea of how the characters came about. (If you aren’t near an MTR train, you can download a copy of the map here.)
