Modern-day Su Minghua accidentally travels back to 1978, arriving in a poor rural village where life is difficult and family and neighborly relationships are strained. At her lowest point, she becomes bound to an agricultural supply exchange system that allows her to exchange things like withered grass for food and other necessities. Turning over a new leaf, she establishes family rules and encourages everyone to work diligently and live harmoniously. She exchanges supplies for meat, improves the soil and water conditions of farmland, and cultivates high-quality orchards, leading the Su family out of poverty and into prosperity. Kindhearted and generous, she also helps her neighbors and provides employment for struggling village women, leading multiple households toward greater income and a better life. The mother-in-law who was once despised transforms into a warmhearted matriarch respected by her entire family and praised throughout the village.
