I think you sing better than Shanghai Rainbow Choir does in this specific song. In particular,the tenor got beautiful and pure voice. Also , the harmony is quite impressive.
非常和諧的女生合音! 尤其基礎的女中低音部,母音很共鳴很美! 伴奏的音質與量與人聲真合諧! 不同的語言在母音的拿撂,乎尾音很美的共鳴而弱止! Be blessed Awesome ! How can build into local children's heart ? The only voice culture can be beded into a primary heart , I hope !
