Math Genius Reborn in 1920s Shanghai

Mathematics professor Fu Yanqiu is sent back to 1920s Shanghai after a bizarre incident where she poisoned herself by licking her lips. Reborn as the long-lost true daughter of the famous Fu family, she refuses the feudal arrangements of foot binding, marriage, and learning etiquette. Using her extraordinary mathematical talent and sharp modern mindset, she confronts the family, fights off green tea tactics, and breaks through the school gates, ultimately achieving self-worth and striking back against feudal customs.
