In the late 1970s, two families, Zhuang and Lin, lived in an alley in the family area of ​​a cotton spinning factory in Suzhou.As the college entrance examination resumes, Zhuang Chaoying and his wife Huang Ling, who are teachers, make their children's college entrance examination their top family priority. Influenced by this, neighbors Lin Wufeng and Song Ying's family also began to pay attention to their sons' studies.

The family of Zhuang Chaoying and Huang Ling seems to be harmonious and decent. Their son Zhuang Tunan is hardworking and studious, and their daughter Zhuang Xiaoting is well-behaved and sensible. However, Zhuang Chaoying's cowardice, stupidity, and filial piety have hurt the family.Lin Wufeng and Song Ying's family next door seem to be going their own way, and their son Lin Dongzhe is extremely naughty. In fact, the husband and wife support each other, parent and child respect each other, and the family is lively and complete.

Lin Wufeng and Song Ying followed the changes of the times and moved their families to Guangzhou to look for new opportunities. After childhood sweethearts Zhuang Xiaoting and Lin Dongzhe separated, they discovered their feelings for each other and agreed to be admitted to the same university. When they graduated, they remained firm despite the obstacles of family and reality.Choosing each other, Zhuang Tunan and Li Jia finally got married after many years of separation.
