In 1966, in a small village in Northeast China, five-year-old chubby little girl Zhou Jiayao is mischievous and possesses astonishing strength, with an overbearing big white goose and a frog following her around. Growing up in the pampering of her family through all sorts of ruckus, relying on her innocence, cleverness, and supernatural strength, she creates one hilarious story after another. Her uncle Zhou Qiangxu both dotes on her and finds her helpless, leading to a wildly chaotic time for the uncle and niece duo. As Jiayao continuously stirs up trouble, heads into the mountains, and visits the market, a wonderful growth story belonging to the little chubby ball unfolds.
