In the late 1970s, the Zhuang and Lin families lived in an alley in the family quarters of the Suzhou Cotton Mill. Just as the college entrance examination was resumed, Zhuang Chaoying, a teacher, and his wife Huang Ling regarded their children's college entrance examination as the top priority of the family. Influenced by this, their neighbors Lin Wufeng and Song Ying's family also began to pay attention to their son's studies. Zhuang Chaoying and Huang Ling's family seemed harmonious and decent. Their son Zhuang Tunan was hardworking and studious, and their daughter Zhuang Xiaoting was well-behaved and sensible, but Zhuang Chaoying's cowardice and foolish filial piety hurt his family. Lin Wufeng and Song Ying's family next door seemed to be doing their own thing, and their son Lin Dongzhe was extremely naughty, but in fact, the couple supported each other, and the parents and children respected each other, and the family was lively and perfect. Lin Wufeng and Song Ying followed the changes of the times and moved their family to Guangzhou to find new opportunities. After childhood sweethearts Zhuang Xiaoting and Lin Dongzhe separated, they found their feelings for each other and agreed to enter the same university. When they graduated, they still firmly chose each other in the face of family and reality. Zhuang Tunan and Li Jia finally got married after many years of twists and turns.
