Who sang the female voice in Jay Chou's Cowards? Attached is her information, thank you.

Nickname, half-day eagle.

Birthday,1994 May 3rd.

A constellation, Taurus.

Sister, Snoopy Yu-

Actually, my cousin never showed up from beginning to end. Singer Viann, Jay's colleague in Alpha Company, sounds like a child. But I don't know if it's because of her looks. A girl named Li Jiaying (whose name I'm not sure) was invited to perform in the MV. She is a professional actress. Similarly, at the concert, she also lip-synched. Jay's cousin has never shown her face.

Jay Chou likes to rap, and prefers to let children sing. The female rapper in Grandma is named Viann, whose age is unknown, and she doesn't sound more than seven years old. It is said that she is a relative and niece of Jay Chou. In the previous album "Coward", the chorus was written by Yu Ni. Viann never appeared in public, but Yu and Jay Chou were on the stage during the incomparable concert.
