This book combs Du Yuesheng's complete life trajectory from the late Qing Dynasty to the Republic of China, and uses deductive techniques (the real information is mainly historical materials) to restore his historical process from the bottom of society to the core of power in Shanghai. Du Yuesheng was born into poverty and lived at the bottom of Shanghai to make a living in his early years. Later he joined the Youth Gang. With his wisdom and business skills, he gradually became a celebrity in Shanghai. Together with Huang Jinrong and Zhang Xiaolin, he was known as the "Three Tycoons of Shanghai", which profoundly affected the social order, economic structure and folk ecology of Shanghai during the Republic of China. It comprehensively presents its multiple roles in gang management, industrial expansion, and social affairs, and objectively reviews its patriotic stance and social contribution during the Anti-Japanese War. It also does not avoid its historical limitations of relying on the old forces and getting involved in gray industries (when reading this book, you should refer to historical data. This book is purely a deduction. If there is any infringement, please contact us in time to remove it from the shelves).
