In Nanjing in 1928, Ge Xiaowei, the owner of a silk and satin shop, returned from studying abroad and met Wang Feifei, an orphan who sang Pingtan in the Confucius Temple. The century-old foundation of the Ge family is facing the impact of foreign cloth. Xiaowei's insistence on reform is blocked by his conservative uncle. Wang Feifei is accidentally revealed to have a secret relationship with the Ge family's ancestors, and the two gradually fall in love while revitalizing the family business and solving the mystery of their origins. When Xiaowei discovered that his father's sudden death was related to the theft of silkworm seeds thirty years ago, the silk shop along the Qinhuai River had already been soaked by the tide of the times. The faded ink marks in the old account books, the land deed codes hidden in the Pingtan Ci plaques, the bloodstains in the abandoned silkworm houses in Purple Mountain... In Jinling City, where cheongsams and suits alternately flow, they will eventually unravel the grievances that last longer than silk.
