Li Yin was born on 18 February 1989 in Sichuan, China. She grew up in a musical family, as both of her parents were professional violinists. As a child, her parents took her to their rock concerts and exposed her to a variety of music. At three years old, she began to learn the violin. Li Yin liked classical, American and European music so much that she says she never sang children's songs when she was a child.
