Yifei, also known as Crystal Liu, is apparently widely known in China as "Fairy Sister" for her appearance. In addition to acting, she's also made a name for herself as a singer and a model.
At age 11, Yifei moved to New York City with her mother, only to return to China a few years later in 2002 to pursue her acting career. The 30-year-old actress' most recent credits include movies The Chinese Widow and Once Upon a Time, which earned $82.3 million in China this summer.
She's also a brand ambassador for Dior, Tissot, Garnier and Pantene.
