Liu Yifei is a Chinese actress and singer. Although she is often credited as Liu Yi Fei (traditional Chinese: 劉亦菲; simplified Chinese: 刘亦菲), her legal name is Liu Xi Mei Zi (traditional Chinese: 劉茜美子; simplified Chinese: 刘茜美子: 茜 Xi is from German movie "Sissi" (Chinese translation 茜茜公主—hence the pronunciation of xi not qian; her mother calls her Xixi). At the age of 15, Liu Yifei's role as "Wang Yuyan" in the television series, Demi-Gods and Semi-Devils propelled her to fame in China.

Born at Tongji hospital in Wuhan, China on August 25, 1987, Liu's birthname was An Feng (traditional Chinese: 安風; simplified Chinese: 安风). Her father was a university professor while her mother was a dancer and a stage performer. They divorced when she was 7 years old. After her parents' divorce, Liu lived with her mother, Liu Xiao Li (traditional Chinese: 劉曉莉; simplified Chinese: 刘晓莉) and her name was changed to Liu Xi Mei Zi. She began modelling at the age of 8 and was trained in singing, dancing and the piano. Moving to the United States in 1998 with her mother, Liu lived there for four years. In those four years she went to Middle School 67 Louis Pasteur. She returned to China in June 2002 to pursue an acting career and adopted her stage name Liu Yi Fei. In September 2002, she was accepted into the Performance Institute of Beijing Film Academy at the age of 15, She graduated from the Beijing Film Academy in July 2006.

Immediately following her admittance into Beijing Film Academy, Liu received offers to star in various television drama serials. Her first role on television was in The Story of a Noble Family. Shortly after, she was chosen to portray the role of "Wang Yuyan" in Demi-Gods and Semi-Devils, a drama based on the same-titled novel by the acclaimed wuxia writer, Jinyong. It was this role that established her fame in China. Her fame was further enhanced through her starring role in the 2004 drama series adaptation of the video game, The Legend of Sword and Fairy.

In 2006, Liu starred in another television production based on a book by Jinyong, The Return of the Condor Heroes. After intense speculation on who would get the role of "Xiaolongnü", the part was finally offered to her. She was backed by Jinyong, who felt that she had all the necessary qualities to play the role of the young and innocent "Xiaolongnü". Although the drama serials she has acted in were well-received, the movies she starred in, did poorly in terms of box office takings. The TV drama serials are based on very popular novels, so their popularity is due to the novels themselves.

In conjunction with her acting career, Liu obtained a recording contract with Sony Music Entertainment Japan in August 2005 and has studied singing and dancing in Japan since then. She released her first single "Mayonaka no Door" with Sony Music on July 19, 2006. Recently she returned to China to co-star with Jackie Chan and Jet Li in a Journey to The West movie about rescuing the Monkey King.
