In this combination photo, China's iconic national stadium, also known as the Bird's Nest, is seen during the Olympic Games' opening ceremony (top) on August 8, 2008 and covered in artificial snow on December 16, 2009 in Beijing. The stadium has been turned into a winter playground at a cost of around 50 million yuan (US$7 million) in an effort to attract more tourists during the quieter Christmas and Chinese New Year season.[Agencies]
