Su Xiao, a teacher, is married to Chen Mo, a civil servant in the old city, and lives with Zhang Guilan, her mother-in-law, a retired worker. The mother-in-law is nagging and prefers boys over girls. She has constant conflicts with Su Xiao because of "decorating the house" and "caring for children". It wasn't until her father-in-law suddenly became seriously ill and Su Xiao stayed up late to take care of her and help her mother-in-law handle the medical insurance procedures that her mother-in-law saw her sincerity. Later, Su Xiao wanted to move to a bigger house, and her mother-in-law took the initiative to use her pension money to support her. The two mother-in-law and daughter-in-law changed from "enemies" to "mother and daughter" and lived a peaceful life.
