The story in the book happens deep inside the Daxing'anling mountains. For thousands of years, the Ewenkis made living by hunting and raising reindeer in the vast forest. They raised ferocious dogs to assist in hunting and camp guard. As time goes by and the world changes, the Ewenkis today are no longer hunting and the bloodline of their hunting dogs has ended. Instead, the tall, ferocious Mongolian shepherds who are able to chase away and kill wolves become the new camp guard responsible for protecting the reindeers. They drive off bears coveting the camp and grow into real bear chasers.

Blackcrane is one of the few children's book authors who come from minority groups in China, which makes him special in China's literati. His works always offer a glimpse into "the call of the wild" from the forest in the north of China. In this original full-length children's novel published for the first time, Blackcrane not only focuses on the beauty of wildlife but also emphasizes the emotional connections between humans and animals, allowing children to not only be nourished by literature but gain authentic and accurate information on the broadness of nature.
