Shen Yupeng had been a fake daughter for eighteen years. On the day she was exchanged, the real daughter said, "She is weak and sick, and I'm afraid she won't be able to take care of herself in the city." So she was thrown into Shinian Village in northern Shaanxi. The rats in the dilapidated cave dwellings are bigger than people, and the yellow wind and sand are blowing so hard that they can't even open their eyes. The village party secretary Zhao Dehou handed her a work point book: "If you don't have 300 work points at the end of the year, don't even think about returning to the city." What can a sick man from the city do? Everyone in the village was waiting to see her starve to death. But when Shen Yupeng woke up from hunger in the middle of the night, a bunch of ancient recipes suddenly exploded in his mind - sour soup, buckwheat noodles, pickled pickled vegetables with spicy oil, and each dish was full of the fireworks of northern Shaanxi. The first time I tried to make millet porridge, the fire was so strong that it burned through the pot, and the black smoke caused the whole village to come to put out the fire. But the burnt fragrant rice oil left at the bottom of the pot made Zhao Dehou squat down by the stove and lick the spoon three times. Fang Hui, a real daughter, wrote a letter to ridicule: "Is a country bumpkin in a cave worthy of eating in the city?" Shen Yupeng slapped the letter on the chopping board, minced the mutton and mixed it with buckwheat noodles: "Then let the whole village have a taste of what is real - northern Shaanxi on the tip of the tongue." When the county leaders came to inspect and were so impressed by the delicious bowl of mutton that they wanted to build a canteen, Zhao Dehou quietly stuffed the recommendation letter for returning to the city into her pocket. Shen Yupeng folded the letter and took another spoonful of spicy food: "Don't worry, I will first pay back the eighteen years that the real daughter owed me, spoonful by spoonful."
