When the orphan Man Bao is picking up waste products in the middle of the night, she picks up Ji Chengchuan, who is heavily injured and unconscious, on the roadside, stubbornly mistaking him for her own father, and even fetches bandages to wrap him into a mummy. Relying on her naive imagination, she uses a toy knife and silver needles to treat Ji Chengchuan's wounds. After Ji Chengchuan recovers from his injuries, he takes Man Bao back to a luxurious villa. This picked-up father also successively helps her find three capable older brothers. Little Man Bao, relying on the family she picked up, henceforth no one dares to bully her in Longcheng.
