After his divorce, Xia Donghai (Gao Yalin), a children's director, returned to China with his son Xia Yu (You Haoran) to develop his career and reunited with his daughter Xia Xue (Yang Zi) who grew up in China. Later, Xia Donghai married Liu Mei (Song Dandan), the head nurse of a hospital. Liu Mei was also divorced and lived alone with her son Liu Xing (Zhang Yishan). In this reconstituted family of five, both husband and wife are very concerned about the healthy growth of their children, but their educational methods are different, and the children are very naughty, which has caused many hilarious but thought-provoking stories.
