Gu Siqing, an urban white-collar worker, was accidentally reborn as an eight-year-old rural girl in the 1980s. She returned to a point where her family was ordinary, her mother was favored by her grandmother, and her eldest sister was unkind to everyone. With her adult mind and understanding of the future, she resolved family conflicts, helped her eldest sister get rid of her scumbag fiancé, and encouraged her conservative parents to seize the opportunity of reform and opening up and start a business in the south. Starting from proposing to sell down jackets, Gu Siqing led her family to overcome difficulties and get rid of poverty, and steadily moved towards the goal of "buying a courtyard house in Kyoto", opening a wonderful chapter in the family's counterattack and living a good life.
