Hua Chong is an older unemployed vagrant. There is only one person in the world who can control Hua Chong - his five-year-old daughter Hua Duoer. Hua Duoer is a piece of gummy candy. As long as she doesn't go to kindergarten, she has to stick to her father all the time: she has to sleep next to her father at night, ask her father to dress her in the morning, eat breakfast with her father, her father must send her to kindergarten, her father must be the first to pick her up after school, and her father must tell her stories before she goes to bed at night. As long as her father is at home, he must be in her sight all the time. In the end, Hua Chong turned around and, with the help of his daughter, became a competent husband, a good father, a professional bodyguard, and established his own professional bodyguard company; his daughter Hua Duoer finally overcame her little problems and became an independent and good child under her father's training.
