Time Travel in the Examination Room The story tells the story of Wen Jingshu, an English graduate student in 2024, who unexpectedly traveled to 1970 amid the frustration of finding a job and failing the public examination. She became a 20-year-old graduate student majoring in trade economics in Qingping County. She has a happy family: her father Wen Zhongping is the director of the County Public Security Bureau, her mother Lin Qingjun is the section chief of the County Agricultural Bureau, and she has two brothers who are not her biological children but care about her - the eldest brother Xu Yanan is the battalion commander of a military region in the Northeast, and the second brother Wen Yanhe is the chief surgeon of the County People's Hospital.
