My mother always compares other people's children. One day, my mother got a mysterious ring. When she mentioned other people's children to her children that morning, the ring suddenly glowed. She suddenly discovered that other people's children had been exchanged with her own children. The other people's children were having breakfast at their own home, and the family thought it was completely normal. However, her own children went to live in other families and called themselves aunties. A series of fantasy stories happened next.
Concept: Parents always think other people's children are good, so how can they really exchange children...
