The book was made as a long gatefold in two sides. In the front side scattered perspectives of riverside sceneries, showing every section of the river originally, while in the back side there are picture related to the river in different times: humans met in a time in a place, rocks showing huge changes in millions of years, or eucalyptus leaves renewing every year. The two-side design shows the artist's practice of seeking for relations between external scenery and inner logic behind it. In the end of the book, a picture of sedimentary rocks gives a imagery expression for the issue the artist was discussing: time must be characterized in a space, and space must be shaped in a time. Their intertwining relationship will not be changed forever.
