On January 31, 2008, Swiss curator, critic and historian Hans Ulrich Obrist conducted a "marathon" of conversations in Beijing, after the example of his famous Serpentine Gallery marathons. This marathon called on artists, cultural producers and media practitioners to discuss the post-Olympic state of the city. Participants included internationally renowned artists Ai Weiwei and Cao Fei, writer and publisher Hung Huang, fashion designer Zhang Da and many others. Topics discussed included everyday life in contemporary Chinese society, the impact of the Olympic Games and the role of the internet in daily life.
