The land shows the accumulative soil erosion of many years, and the underground water trace evokes the image life and presents the history and memories of the past. In the piece, “Time Light,” the artist team utilized bamboo, wood, and iron to make the shape of a seed rising from the ground overlapped with a light trace. The path which is transformed from the sprouting stem invites viewers to enter this space which is illuminated by the light trace. In the space where the path moves, time travel and traces are extracted. The shape reflects waves on the ground via the lighting shadows of overlapping and colliding natural materials, symbolizing life on the land.
