In 1974, educated youths Chen Jianhua and Zhou Xiaoyun met at the Baihua Forest Farm in Beidahuang. Two young people from the south warmed each other in this ice and snow and made a lifelong promise. After returning to the city, they devoted themselves to national construction full of ideals and left their eldest daughter Chen Nianbei to be raised by their grandmother in their hometown. With the birth of the second daughter Pandi, the third sister Zhaodi and more children, this family longing for a son struggled in the changing times. The ridicule of Zhao Youcai, the old enemy at work, the gap between urban and rural areas, and the fate of each of the five daughters, weave into a family picture that spans half a century. When the last child was born, Chen Jianhua and Zhou Xiaoyun suddenly discovered that the happiness they had been pursuing had long been hidden in those neglected daily lives.
