Did you hear that that little Chinese girl who was singing was also lip syncing? Apparently the real little girl who sung was too ugly to be on the stage, her teeth where crooked they said! Wouldn't surprise me if what Lang Lang did was also prerecorded.
These China games are a little strange don't you think? The stadiums are very empty because of security issues, they are going so far as to hand pick people to go into the stadiums to cheer. The atmosphere of these games are very lost I feel.
