In the early years of the Republic of China, society was in turmoil and the people were in dire straits. China's largest city, Shanghai, gave birth to a group of tyrants and monsters who were able to navigate both black and white. They used various means to form gangs and did all sorts of bad things. They colluded with and fought against each other in the bizarre foreign world, forming a huge power network that had a great impact on Chinese society. Du Yuesheng and Huang Jinrong are the representative figures. This book allows you to further understand that period of history through their narration.
