Cai Yuan and Jian Jun Xi are two Chinese-born artists, based in Britain, who work together under the name Mad For Real.

They have enacted (unofficial) events at the Venice Biennale and the Turner Prize, where, in 1999, they jumped onto Tracey Emin's My Bed installation.

Originally finding fame as performance artists specialising in art intervention, they have since diversified, engaging in numerous works in both Asia and Europe.
