When the steel-making mill refines steel, high temperature melts down scarp steel, and the residual metals left on the billet are called “residual gold” in terminology. The appearance of residual gold shows the mobility of the substance and the state of instant coagulation after cooling down. Its surface is organic and irregular, acutely displaying a kind of primeval tension between matters.

The work draws support from the residual gold with irregular appearances and arranges them to simulate the natural terrain and underline the cultural connotations behind it. Also many little humans of steel are put on to make the domain of the work become a strong bond between steel and human and to refer to the fact that the material surroundings or steel which human create bring on the world of civilization.
