Pairs of dancers perform the grand tap dance of the classic repertoire Irish Riverdance, as its prelude to tour show around more than a dozen cities in China, at the Grand Theatre of Shenzhen, south China's Guangdong Province, Dec. 8, 2009. Riverdance is a theatrical show of traditional Irish step dancing, notable for its rapid leg movements while body and arms are kept largely stationary. The performing team for this China tour show mainly consists of Irish elite dancers, together with superb dancers from Europe, north and Latin America. [Feng Ming/Xinhua]
