Orphaned at the age of ten, Su He lived with her uncle's family for ten years, fetching water, splitting firewood, feeding pigs, and farming as cheap labor. One day, she was traded for a betrothal gift of 180 yuan and married off to Shitou, a demobilized soldier with an old leg injury who was left discarded in the woodshed. While the whole village calculated whether she was worth the money, only Shitou dragged his injured leg to clear half a step of the road for her. On their wedding night in the woodshed, two people cast aside on the edge formed an alliance. Relying on the herbal medicine identification skills passed down by her father, Su He ventured into barren slopes and deep mountains, starting from setting up a stall to sell medicinal meals, and step by step established the Su's signboard. Guarding a ledger of clear accounts and the conscience that daily food should not be sold as medicine, she saw through those making trouble in the dark and pulled her family to turn a bitter life sweet.
