A top student in modern management died in an accident and woke up as Su Qiaoqiao, a widowed sister-in-law from a poor and scholarly family. The beginning is hell mode: the husband dies early, the family is destitute, and there is a lot of debt. The family's only hope is the pedantic and naive brother-in-law Lu Zhishu who knows nothing but reading. Seeing that the creditors were about to come, Su Qiaoqiao gritted her teeth and decided to return to her old career - applying management and project promotion techniques to her brother-in-law's preparation for the imperial examination!
She formulated KPIs, introduced the "PDCA" cycle review method, opened a "modern postgraduate entrance examination training class", and used incredible devil training and business models to lead a group of crooked students on the road to counterattack. The main plot revolves around how Su Qiaoqiao used modern thinking to transform ancient education, turning a bookstore on the verge of bankruptcy into the world-famous No. 1 Academy. In the process, she helped her brother-in-law and a group of students realize their ideals in life, and gain a funny and inspiring story of their own career and love. The highlight is the collision between modern management knowledge and the ancient imperial examination system, as well as the ridiculous daily life between the "King of Juan" sister-in-law and the "Lingping" brother-in-law.
