A small town in the south of the Yangtze River, the river port and the railway tracks are intertwined, and the old sails and whistles sound at the same time. Yuncang originated from the prosperity of the waterway and ended with the wind of the times. Liang Shiyu came from a silk and satin family in the west of the city. When he was a boy, he watched his father and guild guarding the dye vats and machines leaning against the city wall, and watched the railway surveyors come walking through the mud carrying tripods. He hesitates between his family business and a new path, and wavers between his family and his personal love. The companions include Xu Yun, who has been looking up at the clouds since she was a child. She has learned surgery, and there is often a thin line between saving lives and saving hearts; Chen Jinzhi, a tabloid writer, drinks bad wine to write harsh sentences, and stops writing on the edge of a knife several times; and Liang Heng, who walks out of the silk reeling shed, copies short guns and sings long songs. From the late Qing Dynasty to the Republic of China and then to the new regime, Yuncang experienced the ebb and flow of war, famine, guild strikes, inflation, repression and liberation. Everyone has edges and corners worn by the sand in the intertidal zone, but when they look at each other, there are still sparks in their eyes. The sound of the tide entering the city is not only the sound of railroad tracks and steam whistles, but also the sound of fate knocking on the door. This is the mutual fulfillment and sacrifice of a family and a city, the mutual reflection of scenery and people's hearts, and the story of how an era gradually changes the footsteps of the old to a new path.
