In the summer of 20 16, Lin Jingyun, a Chinese food critic who grew up in France and a senior editor of Gourmet magazine, came to Shanghai to visit food and start a journey of seeking roots. At this time, the Lins' old house has been transformed into a restaurant, which is full of precious old Shanghai newspapers and old things, recording the stories of that year. Lin Jingyun stumbled upon a diary and opened it. It tells the story of a girl named Tianying's ups and downs of love legend. In Shanghai in the late 1920s, the Hong gang, the Lin chaebol and the Xu police station stood on the beach, calm and undercurrent. In the theater, Tian Ying disguised herself as a male makeup artist, nine-year-old Hong, and went to the stage to save the scene, but she didn't want to be an instant hit and become a famous figure. It also made the red gang master Luo and Xu Xingcheng, the son of the Xu family, fall in love at first sight and learn from each other's strengths. The eagle seed of love thought that Xu Xingcheng, who was gentle and elegant, would be a sweet first love, but it turned out to be a scam. It happened that Luo Zaiquan, who has always been domineering, met unexpectedly and became entangled. Unconsciously, Tianying's inner emotional balance is also quietly changing. At the same time, Duan Tianci regarded Tianying as his fiancee and imprisoned her in the name of protection, but broke through her kindness, kidnapped her and drew a clear line with her. Hong's daughter secretly loves Luo and makes things difficult for her everywhere, but she is moved by her true temperament and her rival in love becomes a close friend.
