This BBC News series 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 the big attractions for visitors to Hong Kong is the 'Symphony of Lights', a spectacular sound and light show that takes place every night on Victoria harbour and is claimed to be the world's largest permanent display of its kind.
More than 40 high-rise buildings are lit up for the show, which is usually a hit with tourists - but for residents, there are concerns about the financial and environmental costs involved, as Vaudine England discovers.
