Drawings from Underground City by Xinyang Chen, a place for "cowards and mad men" who are running away from the surface. "Form follows dirt" she says.
Underground City is a dark place for leftover people, especially those who scared by the above ground world; themes of it are hidden and discover, stolen and intimate, lost and vanishing. The thing underground citizens ( people call them coward or madman/woman ) do is wonder around; there do have some interesting places to go. For example, a museum of thing should be forgotten. The underground city could under anywhere, but i would like to let it under midtown Manhattan.
