The old house has strange mold marks that condense into strange human faces, and leaky rusty pipes drip water day and night. Lin Xian, a down-and-out father, lives in a shabby house with only his four-year-old daughter Nuan Nuan by his side. Coarse cloth and old clothes, three meals a day are hard to come by, and the words "hungry" from a child reveal all kinds of embarrassment in life. In the days of dilapidation and poverty, father and daughter stayed together. In a desperate situation, Lin Xian was determined to make a living and turn his life around.
