In 1983, in a county town in southern China, Lin Xiaoman, an overworked corporate drone from the twenty-first century, wakes up in the body of a village girl whose greedy relatives have seized her family property and are forcing her to marry an old bachelor. The original owner drowned herself in a river, leaving Lin to pick up the pieces. Fierce and overbearing on the surface but shrewd and calculating inside, she possesses a special ability called "Precise Valuation": touch an object for three seconds, and she knows its cost, selling price, and the best time to sell it. She starts out selling odds and ends at a street stall, specializing in "junk" that nobody else wants, then reselling it for twice the price and leaving her mocking relatives speechless with rage. When her aunt tries to take over her stall, Lin lets her think she's getting a bargain, then exposes her dirty secrets in front of everyone. When her cousin steals her supply sources, Lin uses her ability to snap up even cheaper goods. When her grandmother demands bride-price money from her, Lin slaps the account book down on the ancestral hall table. Rumors, denunciations, and underhanded tricks: every attempt to make things difficult for her becomes free publicity. From a street stall to a wholesale shop, from a ten-thousand-yuan household to the owner of a private factory, she buys a three-story building on the county town's busiest street and opens a department store, making the relatives who once called her a "money-losing burden" line up to work for her. Yesterday, you wouldn't give me the time of day. Today, you're not worthy of me. Watch the top female profiteer of the 1980s use clever tactics to put people in their place and turn her life around through sheer ability.
