The whole book is created based on American experimental composer John Cage' three-movement composition 4'33". It is commonly perceived as "four minutes thirty-thre seconds of silence." However, the critical point is the sounds of the environment during the four minutes thirty-three seconds of silence. "I have nothing to say and I am saying it and that is poetry," he said. That may explain his creative concept. I took the 46 letters in the sentence, arrange them in different shapes and orders.

That's what I feel in 4'33", what I feel in silence. Nothing is everything; one sentence could be various and everything.
