It is a refreshing time-travel novel for women with the background of "Love in the Courtyard". Lin Wanqiu, a modern law graduate and food blogger, accidentally traveled to a courtyard house in 1965 and became an orphan who had just lost her father and been abandoned by her stepmother.
Facing the moral kidnapping of Qin Huairu in the hospital, Jia Zhang's voyeurism, Xu Damao's hooliganism, and Yi Zhonghai's hypocritical calculations, Lin Wanqiu has no superpowers, but relies on modern legal knowledge, business acumen and prediction of the plot of the original drama to fight back step by step. She used the "Constitution" and "Public Security Management Regulations" as weapons to overturn the unreasonable demands of blood-sucking insects; she relied on improving cake stalls, opening tailor shops, and contracting factory canteens to counterattack from being penniless to the "invisible rich woman" in the small courtyard; and with accurate predictions and calm layouts, the calculators reaped the consequences.
