This book is called "The Biography of the Heroes of Taihang" and was commissioned by several people who experienced it more than thirty years ago. Shen Shenhuo spent most of his life hanging out among the humble laborers. He thought of his predecessors who were not afraid of death and hardship, and worked hard with their heart and soul. Their iron horses stepped on the glaciers, their tyranny sharpened their frost blades over thousands of years, their goshawks roamed the desert, and their majesty swept through China for generations, so it is also called "The Legend of the Dragon". The author recalled his half-life experience, in which he felt that people were at odds with each other and always wanted to kill others in critical situations, so he named it "The Survival of a Cow".
