In the early 1990s, on the eve of the restructuring of the old industrial base in Northeast China, factories stopped production and workers were laid off. On the frozen black land, order collapsed and rivers and lakes emerged. A group of men who came out of shantytowns, machine tool factories, and coal mines fought on the edge of loyalty and interests, survival and destruction. This book uses the growth of the protagonist Chen Beifeng as a line to restore the Northeast gangsters' 20 years from gathering righteousness and expansion of power to collapse. It writes about the hypocrisy and hotness of morality in the world, the hotness and coldness of brotherhood, and the tragedy of the fate of little people who have nowhere to escape under the torrent of the times.
