The creation of performance art lies in its contingency. From Dada who innovated for resistance to John Cage who innovated for innovation, the concept of artistic performance has a long history. This behavior originated from the daily life of the exhibition. We used the old factory building as the exhibition hall, and it was inevitable to clean the broken cement floor. There was a place where the loess was difficult to clean and flowed out a pool of hum that seemed to explode, like the traces of a blast with gunpowder when we were young. From minding it to playing with him, it is an interpretation of daily life as art.
