This book is a literary work that may describe the growth process of a boy who makes a living by pulling fibers on the river. The background of the story may be set in a specific historical period and geographical environment (such as the Rhine or Danube river basins in Europe). Through what the young trackers see and hear in their hard work, their complex relationships with boat owners and companions, and their adventures on fast-flowing rivers and steep riverbanks, the work may show the tenacity of the young trackers at the bottom, their desire for freedom, and their ups and downs in the torrent of the times.
