The title of my work is trace. Each day limited time passes away at an extremely fast speed. Our perception of time varies with the time zone. It also varies with the flora and fauna or our feelings, as well as the regions, countryside or urbanity. My work records time through numerous lines or the act pf drawing these lines. The viewers are supposed to feel the passing of time. I want to convey the changes brought by the growth, withering and decay of plants and scenery or even human feeling due to passing time.
