Sun Yuan and Peng Yu are Beijing-based contemporary conceptual artists who are known for their controversial approach to installations and interactive projects. Working collaboratively, they won the Contemporary Chinese Art Award in 2001 and were the representative artists at the Chinese Pavilion in the 51st Venice Biennale. They are also known to take on unusual materials like human fat tissue, live animals and even baby cadavers. Their artwork deals with issues of life, death and the human condition in surreal, and sometimes confrontational, ways. Their works have been collected internationally, including the acquisition by the Saatchi Gallery of Old Folks Home, which features thirteen life-like sculptures sitting in their mechanized wheelchairs.
