moreover, lin miaoke and yang peiyi are both at the top of their class in school...lin wants to be a doctor and yang wants to be a teacher. both can succeed in their dreams no matter whether or not they continue their acting and singing.

Yes, Yang Peiyi was known for her stage fright. In one of her previous performances she started to cry as the song began and a few times her voice didn't come out fully in her performances because she was nervous. However, her voice really is amazing. I think what would be acceptable is if they pre-recorded her but have her stand there and lip-synch to her own voice.

Lin Miaoke is not just a pretty face like most people think. She is actually a child actress and had already acted significant roles in two tv shows and signed the contract for another movie before the olympics. Since then she has starred in three more tv shows and one movie. She can cry whenever the script states. however, her singing voice is extremely average, maybe even less than average. if China wanted to use her in the ceremony because she is a child star, fine, but don't let her "sing". any other role in the ceremony would be just as well.

or what about a duet? a child star singing with a girl with an angel's voice.

moreover, China is a large country...i have seen many girls prettier than miaoke and nicer voices than peiyi...they couldn't find a girl who was both?
