Financial analyst Lin An accidentally transformed into a twelve-year-old girl named An Qian during the Jiajing period of the Ming Dynasty. She lives in a prosperous place in the south of the Yangtze River, but her family is in decline. Her mother died young and she lives with a father who is "not doing his job properly." This father, Ye Wentang, seems to know a little bit of everything besides studying and taking the imperial examinations - he knows a little bit of boxing and kicking, knows some herbal medicine, and can even repair farm tools and do accounting and financial management. He is somewhat mysterious among the neighbors. However, in an era when "everything is of inferior quality, only good education", a father from a "miscellaneous family" who failed to pass the imperial examination means that his daughter An Qian's future is gloomy.
