The story of Egret takes place in Shanghai after the Central Plains War. The warlords in the mainland are fighting each other, the gangs and the Sichuan warlords are using each other, the conflicts between the gangs and the concessions, and the influence of finance on the Chiang Kai-shek regime. Transportation of opium and soil, arms trafficking, assassinations, labor movements... The egret's glory is a flower blooming in a complex social environment.
