Ah yes. Hong Kong adverts are mostly rubbish, but I did see a few absolute gems.
The best being an MTR (underground) ad for the discovery channel.
They basically created a flick book advert that was posted and lit up for a stretch coming into Causeway Bay station. You look out of any window on that side of the train and you can watch the ad as you move.
Fantastic creativity and placement. Seriously brilliant. Id love to see that concept on the Underground here!
