The story is set in Shanghai and Nanjing from 1920 to 1937, with warlords fighting and the rise of national industry as the background. The feasting and feasting on the Bund in Shanghai are in sharp contrast to the hunger and cold in the slums. The establishment of the National Government in Nanjing brought a brief period of stability. At the same time, the undercurrent of Sino-Japanese conflicts gradually escalated, adding a sense of the times to the story.
