Zhou Meihua, a retired strong woman who is vigorous and resolute at home and is very professional at home, moved in with her children. Her arrival was like a huge stone thrown into a calm lake, causing huge waves. From her children's careers, marriage and love, to the education of her grandchildren, and even the ecology of the entire community, everything has changed because of her. From the beginning, the children "cannot afford to offend and just want to hide", but later gradually discovered that this "untouchable" mother is the most solid backing and the warmest harbor in their lives.
