On the north bank of the lower reaches of the Yangtze River, there is a group of only children born in the 1980s - Zhong Li, Yamin, Yu Ling, and Zhong Yuanyuan. They were born and grew up in the countryside. They are the only treasures of their families, but they find the warmth of brothers and sisters in each other. Going to college, getting married and having children, buying a house and paying off a mortgage - every step is based on the beat of the times.
