Cast members of the music drama "Red Star Over China" are seen during a press conference in Beijing, capital of China, June 23, 2011. The play, which is adapted from American journalist Edgar Snow's homonymous book, will debut in Tianjin on July 1, 2011 to celebrate the 90th anniversary of the founding of the Communist Party of China (CPC). Snow's "Red Star Over China" is a vivid account of the CPC leadership based on the months he spent in Yan'an, the center of the communist revolution before the founding of New China, in 1936.
