I found a music video while searching materials for my work. The music video titled "Loving You". Minnie Riperton is the original singer of this wonderful song. Shanice and Leona Lewis are among the singers who sing this song too. To my surprise, there is a chinese female singer who also capable in singing the whistle register part of the song. She is Jane Zhang. Below is the link of her performance.
