Under the Manhattan bridge, I use the famous Jack Daniels whiskey as ink, the wall and ground as paper scroll, wrote down a third century story about "一叶障目 "（One Leaf Blindfold）- a well known idiom from a Fifth century BC and has been passed down to the present day.
 
The words were continually written down, and the strong aroma of whiskey spread out to the space. Soon afterwards, the writing and aroma fading away as they evaporate, eventually leaving nothing behind, like nothing happened before.
