Qi Maisui suddenly dies and enters the 90s parenting literature of a famous family. She becomes a temporary nursery worker who will be blamed at the beginning, but she can understand the pain, fear, suffering and choking of children under four years old. The young master of the Bai family cried until his face turned purple, and nineteen of the twenty nannies withdrew. The original plot waited for her to be kicked out of the compound for "tampering with entrance objects". She didn't talk about metaphysics, she just turned "pillows stuck, milk was bitter, and the smell of medicine on the cuffs" into evidence, sealing milk cans, changing pillowcases, and establishing rules in public. After ten minutes of stopping crying, she took the contract, phone number and access rights, and started to save her job by starting a babysitting business that the famous Qinghuai family could not find.
