The Caochangdi branch of Beijing Design Week is an eclectic mess. The posters have the wrong dates. Designers didn't finish their work on time, so you'll find empty spaces in the place of installations. Volunteers might sell you a button or a program that's supposed to be free. You'll wonder what some exhibits, such as a mishmash of geolocation balloons and a physical "chat room" called "The Real Network," have to do with design.
Mix it all together, and you have a wonderful template for the best and worst of Beijing.
