In the 1980s, He Suyun returns to life after being reborn, only to find her family burdened with a huge debt. Creditors arrive to seize the stone mill that sustains her household. With three children to feed, she struggles to make ends meet by handcrafting tofu, rushing to the market by day and grinding soybeans late into the night to repay the debt and save the mill. Rival sellers maliciously slash prices, imitate her packaging seals, and produce counterfeit goods to ruin her reputation. The debts left behind by her elder brother come back to haunt her years later when he conspires with outside buyers and uses forged documents in an attempt to seize her workshop. He Suren stands firm on quality, keeps careful accounts and evidence, and joins forces with women from the village to build a sustainable business. With a reliable supply, she secures a long-term contract with the county food supply station and officially registers a tofu workshop. Through her tofu-making skills, she breaks free from hardship and leads her family and neighbors toward prosperity.
