行为，透明胶水，灰尘，可变尺寸，2009
Action, Glue, Dust, Variable, 2009

用胶水在玻璃上写上“时间是检验真理的唯一标准”，随着时间推移，风沙会将这句话逐渐显示出来。
The sentence - “Time is the sole criterion for testing truth” - was written on the glass with glue. Over time, the sentence has gradually turned clearer as more and more dusts attached to the glue.
