By the Seine is destined to be a modern biographical novel steeped in nostalgia and infused with classical Western European elements.
It tells the thrilling, heart-stirring love story of Li Zhongtian, a renowned Chinese silk fashion designer and company president, nicknamed Xiaotian, and Ming Kexin, a famous Chinese-French writer living in Paris, France, nicknamed Yue'er. Both have fathers whose lives were shaped by the Cultural Revolution, a turbulent period in Chinese history. Their romance is also opposed by her parents, who hold high positions in French society, and by her ex-boyfriend. When the heroine is stricken with a strange, terminal illness, the two stand side by side, fighting both the disease and the ugliness of reality, and ultimately achieve success in both their careers and love.
