We can conclude that "Return to the City in the 1980s" is a sweet novel about Su Yan bringing her two children back to the 1980s. In the story, Su Yan met her father, Gu Ye, a soldier. He fought for his wife and children on the battlefield, but when he returned home, he found that Su Yan had been forced out of the house by his scumbag father. The story revolved around how Gu Ye remarried Su Yan and how he faced his stepmother and stepsister. However, the specific plot and ending needed to be understood by reading the chapters of the novel, and the search results provided did not provide information about the specific plot. Therefore, we can't give a definite answer to the detailed plot and ending of the novel.
