Shanghai has lots of locations named after water, but "when you actually go there, you realize there is no longer any water", Gong says."We have built a mini program on the mobile mapping service to lead people on a journey through Shanghai, where lots of romantic cultural connections were achieved through the lost waterways."

The theme Bodies of Water is also rooted in the unique historical and geological characters of Shanghai, Gong says. In the grand hall at PSA, a wood boat that used to serve as a ferry from the Dujiangyan area in Chengdu, Sichuan province, hangs from midair. It is the main part of an installation named Water System Museum created by Cao Minghao and Chen Jianjun. The duo, both in their early 40s, have been working together since 2010. For this project they used tents and discarded building materials of the Qiang ethnic people, to reveal the impacts of local policies and post-disaster reconstruction after the 2008 Sichuan earthquake.
