The book uses nearly a hundred independent stories as a carrier, and uses self-narration to reveal issues such as mining disaster management, network management, and overseas investment of the coal merchant class. Chapters such as "Communists", "Poet Gao Tianxi" and "The Farewell of the Gambling King" in the book use character profiles to reveal the conflict games and survival philosophy of this group in the accumulation of wealth, interspersed with observations of social phenomena such as the operation of underground banks and the infiltration of underworld culture. The colloquial narrative is combined with a black humor style, and reflects the original capital accumulation logic and human complexity of the coal industry through cases such as root capital operations and Ma Pengcheng's political and business strategies. The appendix "Four Lessons from Liao Fan" and the mapping of realistic prototypes strengthen the documentary nature and social criticism dimension of the text.
