Fushun is a city affluent in mineral resources. Through years, overwhelming exploitment has badly damaged the land condition. The land subsidence happens everywhere. As a result, a number of villages near the mines has been buried underground, replaced by lakes in various size.
The aim of the project is to make a place for people who formerly lived here to look back. An upside-down cafe above the lake, of which the reflection is just like a pitch house laying in the water. The definitions of public building and memorial object are actually cross programing here.
