In the 1970s when supplies were scarce and people had to buy shoes with cloth tickets, Gu Laoliu was a well-known lazy man in Gujia Village and was disliked by everyone. But in the eyes of three-and-a-half-year-old Chang An, this patchy, even a little unattractive man is the best father in the world. In order to give his daughter a bite of meat, he would be pecked all over the yard by the big white goose of the village bully; he would stuff the family's remaining half of the shabby nest into his daughter's mouth, and his stomach would growl with hunger; although he could not tell the difference between east, west, north and south, he used his strong shoulders to carry a carefree sky for Chang'an.
