This volume consists of three middle-grade stories, "Wolf Walk Thousands of Miles" "A Short Biography of Rooster 'Fighting Tiger'" and "The Ice Fox". "Wolf Walk Thousands of Miles" tells the story of a small pack of wolves rescued by human beings and released into the mountains. Under the guidance of their parents, the wolves grow up in the "greenhouse", gradually adapting to the crisis-ridden wilderness, and live happily. When the hunting dog escapes its owner and returns to the mountains, it destroys the peace and quiet there. A cub is killed, and the male wolf, desperate to protect his son, is killed by a poacher's forgotten hunting gear. Without their tough leader, the "tame" wolves are in an unprecedented predicament. They meander for thousands of miles, and through grueling trials and tribulations, quickly grow into self-reliant hunters and defenders of the mountains and forests. A short biography of the cockerel. "Fighting Tiger" is about the extraordinary adventures of a chicken. Through the whimsical "training" of two urban and rural schoolchildren, this small rooster, which had once circled a tiger in a zoo, nearly became the "black horse" in the "cockfighting" competition. The Ice Fox used to be a hunting dog. After the hunting ban, the village has become a folkloric tourist area, and the ice fox, which used to be favored by the hunters, has been given a cold shoulder. Unwilling to be lonely, it even attacked the pets brought by the tourists, and broke into trouble again and again. Lonely hound finally recovered its nature in nature, found friends, and recovered the happiness belonging to a family dog.
