The play tells the story of Jiang Mulan and her husband and wife, working in Beijing, old and young. Because both of them are the first generation of only children, the burden of supporting the elderly is relatively heavy. Mulan's father, Jiang, suffers from cataract and must take care of her grandfather, Jiang Duofu. Mulan had a conflict with Lucy because of the problem of supporting the elderly. Jiang Mulan's superior, Lei Songhua, is also worried about her parents' affairs and always finds fault with Mulan at work. Lu's father died unexpectedly, so Lu can only take care of Lu's mother himself.
Jiang Mulan met the mayor by chance, which explained her problem. The mayor said that the government has put the issue of providing for the aged on the agenda and will definitely give the people a satisfactory answer. Jiang, who lives in a private nursing home, helps to take care of his son who is away all the year round and becomes good friends with Lei Songhua's parents. The land of the nursing home originally belonged to the municipal planning land and will be demolished soon. Jiang Mulan called the mayor's hotline and the government came forward to save the nursing home. Jiang Mulan finally made up with Lei Songhua. Jiang and Jiang Duofu want to go back to their hometown in order not to drag Mulan down. Finally, Jiang Mulan took her parents back and the whole family was reunited.
