With a sudden thunder, Chen Haonan, the leader of Causeway Bay, fell into the Lannidu Wharf in Shanghai in 1924.
The youth gangs are exploiting the country, the foreign companies are domineering, and the laborers are like grass and grass. Carrying a butterfly knife and carrying the "brothers first" movement in Causeway Bay, he gathered the men at the lowest level to establish a "brothers hall" - no commissions, no bullying, and profit sharing according to work.
The rules of the old world can't suppress the new passion, and the waves of the Huangpu River can't drown the true love. Chen Haonan knew that it was time to use his knife to stir up some different ways of living in the muddy waters of Shanghai Beach.
