Su Wanqing, a modern entrepreneur in ecological agriculture, dies suddenly from exhaustion and travels through time to Qingxi Village in the Great Yan Dynasty, where she becomes a penniless farming orphan with no family or relatives. During a bitterly cold winter, when heavy snow cuts off the village, she nearly freezes and starves to death. Thanks to the kindness of her neighbor, Aunt Zhang, who regularly provides her with food and assistance, she manages to survive the hardest days. Armed with her modern agricultural knowledge and food-processing skills, she refuses to spend the impoverished winter merely gathering wild vegetables in the mountains and preserving them as pickles. Instead, she earns her initial savings, repairs her dilapidated old house, improves the barren farmland, builds insulated seedling greenhouses to grow vegetables out of season, and starts a small workshop producing pickled vegetables and dried goods. With a generous heart, she shares all her farming techniques with the villagers and leads the entire village in growing and selling vegetables.
