Through reinterpreting "the Chinese story" represented in the scroll Along the River during the Qingming Festival of the Northern Song Dynasty, this article tries to answer the question why, in the World Expo 2010 at Shanghai, it could become a "source" to imagine the "city" and even "China." I would argue that its rich and multilayered expressions of Chinese culture as well as politics are the main reasons, especially its obsession with Empire and its sympathy with the daily lives of citizens. In this panoramic painting, the story of Dongjing 东京, the cosmopolitan metropolis of the twelfth century, not only provides new resources for us to rewrite the urban history of China, but also inspires us to rethink the multiple possibilities of modernity in Chinese history. Furthermore, the selection of this scroll to exhibit in the Expo also symbolizes how contemporary China positions itself in the current world stage as well as how it reflects on its own cultural history.
