Five-year-old Jiang Yu has only one dream: to live a simple, peaceful life. Unfortunately, her talent has other ideas. When she wins first place in a competition, all she wants is to make her grandmother, who has come to the city to look after her, happy. She tinkers with little inventions and has seen the big world, but the thing she treasures most is going home to eat her grandmother's braised pork and listen to her parents tease each other in the courtyard. Her grandfather says she is the Jiang family's precious treasure, but she shakes her head earnestly: "I'm just an ordinary child." With her clever little mind and warm heart, Jiang Yu protects her family and brings warmth to those around her, quietly overturning everyone's expectations in her own way. It turns out that true greatness comes from having a gentle heart.
