This is a story of the love of family ties and the beauty of life.
With the end of the absurd years of the Cultural Revolution, the dim marriage of shipyard worker Ding Guangwei and his wife, musician Hu Yushan also broke down. Ding Guangwei left his young son Xiaobao, who suffered from severe hepatitis, and went to South Africa to work. Hu Yushan started a new family with her former lover, liver specialist Wang Nianci. However, four-year-old Xiaobao was sold by an old nanny to Mr. & Mrs. Shen Honggen, and thus lost contact with his biological parents. The honest Shen family loved Xiaobao as if he were their own child, but they knew nothing about Xiaobao's condition, which led to a delay in the radical cure.
