The story takes place after 1949, in the early days after the founding of the People's Republic of China, and the specific time period spans from the 1950s to the 1970s. Cities such as Shenyang and Changchun in the Northeast were full of turmoil and changes during this period, and underworld forces became increasingly rampant. Social transformation and turmoil provide fertile soil for gang organizations. The gang is not only involved in traditional activities such as gambling, smuggling, and debt collection, but is also deeply involved in the city's underground politics, resource competition, and violent conflicts.
