It’s been seven years since Daan Roggeveen and Michiel Hulshof published How the City Moved to Mr. Sun, the story of mass urbanization in China. It looked specifically at the mechanisms behind this phenomenon and the challenge to host the next 300 million people during the coming twenty years (starting from 2010). After Ole Bouman’s reflection on the Venice Architecture Biennale two weeks ago, this is the second prelude to Volume #54: On Biennials with a special on the UABB\Shenzhen.
