In an ongoing series, BBC News focuses on aspects of life in countries and cities around the world. What may seem ordinary and familiar to the people who live there, can be surprising to those who do not.
One of Hong Kong's smartest residential areas is called Mid-levels, and is served by an unusual form of transport: the longest outdoor covered escalator system in the world.
The Central-Mid-levels system consists of twenty escalators and three moving walkways - and it runs in one direction in the morning, and another in the afternoon.
The BBC's Vaudine England explains why the escalators are such an important part of Hong Kong's culture - helped by Andrew Chworowsky, managing director of the Fat Angelo's restaurant chain.
