[00:00.31]When a typhoon strikes,
[00:02.48]one of the best places to be is Hong Kong harbour with its sheltered anchorage.
[00:09.47]
[00:20.01]A centre of international trade,
[00:23.68]the city is famous for its jumble of skyscrapers and its bustling commercial center.
[00:29.10]But there's a side to Hong Kong that's less well known.
[00:35.31]Behind the urban sprawl lies a swathe of wetlands which include the Mai Po Nature Reserve.
[00:50.37]Managed principally for the benefit of migrating birds,
[00:54.11]the reserve maintains a series of traditional prawn farms, known as gei wais,
[01:00.98]and their adjoining mangroves and mudflats.
[01:03.87]Every two weeks from November to March,
[01:10.33]one of the gei wais is drained by opening up the sluice gates.
