About 20 Chinese cities joined a worldwide relay on Saturday night to switch off lights of major buildings for one hour to highlight concerns about climate change while calling for actions.
Tens of thousands of Chinese either turned off lights and appliances at home or joined outdoor activities such as candle-lit dinners and star-gazing parties, to show their support.
The iconic "Bird's Nest" National Stadium and the "Water Cube" National Aquatics Center in northern Beijing, usually illuminated by floodlights, went dark completely at 8:30 p.m. local time (1230GMT).
Dozens of glitzy hotels, office buildings, shopping malls and restaurants in the capital also switched some lights off for 60 minutes.
