In the old China after the Opium War, the country's mountains and rivers were broken, China and foreign countries were mixed, various social forces were prevalent, and all kinds of gangs were rampant. Gangs such as the Qinggang, Hongmen, and Paoge staged scenes of historical tragedies and comedies. This book vividly and detailedly exposes many ugly phenomena of the three religions and nine streams, exposes their organs and layers of disguise, and shows some of the dark sides of old Chinese society and the bitterness of the poor working people living in it. It can be called a masterpiece that reflects the social style of old China.
