BEIJING -- Chinese officials defended their decision to pass off the voice of a 7-year-old songbird as that of another girl at the Olympic opening ceremony, calling it a simple casting choice. Critics said it was a step too far in China's obsession with the perfect Olympic Games. Beijing organizers of the games faced tough criticism Wednesday after a whistleblower revealed that the 9-year-old who performed a song during the spectacular opening ceremony was lip-synching to another girl's vocal track. Yang Peiyi, a 7-year-old with bright eyes and a smile made crooked by the stubs of her first grown-up teeth, was heard by an audience estimated in the billions during Friday night's ceremony, singing "Ode to the Motherland." But they never saw her face. this petition is to let Yan Peiyi know we are supporting her, and to let the world know this was wrong! And perhaps get Yang to sing at the closing ceremonies of the onlympics! thankyou for your support!
