In the autumn of 1977, Shuanghe Brigade of Hongqi Commune, Jiangbei County. Lin Qiaozhen was so hungry that stars appeared in her eyes, and was locked in the woodshed by her mother-in-law Wang Guilan to chop firewood. Five-year-old daughter Li Xiaoya secretly gave her half a piece of roasted sweet potato and said timidly: "Mom, I won't eat sweets anymore. Don't cry." Lin Qiaozhen didn't cry. She touched the personal space hidden in the sweet potato - rice, white flour, pork, cloth tickets, and the White Rabbit toffee that her daughter had never seen before. She began to quietly improve the food, first let her daughter eat meat, and then bought a new cotton-padded jacket for the family. However, her mother-in-law Wang Guilan became suspicious and teamed up with her eldest sister-in-law Chen Qiuping to search her body and scolded her for stealing people to support men. Her husband, Li Jianguo, ignored the incident and slapped him in the face: "You are a hen that can't lay eggs, how dare you hide private money?" Lin Qiaozhen covered her face and laughed. The next day, she took out the family separation agreement in front of the whole clan: "Either we divide, or I go to the commune to sue you for abuse." After the separation, she set up a street stall to sell braised pork, and used the seasonings stored in the space to make braised meat that people from all over the country rushed to buy. As soon as the self-employed sign was put up, someone reported her for speculation. Lin Qiaozhen went directly to commune director Zhou Guoqiang with the braised pork and said, "Try it. If it tastes good, our team will set up a factory together." Three years later, she became the first 10,000-yuan household in the county, and her daughter wore a dress and studied in the best primary school in the county. Her mother-in-law, Wang Guilan, came crying and begged to get back together. Lin Qiaozhen handed over a wad of banknotes: "This is the gift money you gave me when you sold me, and the excess will be calculated as interest.
