At the beginning of the 20th century, everything was unknown, but the times could not stop the arrival of new ideas. Kong Zhaoshou, then president of Hunan First Normal University, invited Yang Changji to teach there. The arrival of a group of teachers who are proficient in Chinese and western cultures has made Hunan Normal University a place for many aspiring young people. Cai Hesen (Xu Liang), Xiao Zisheng (Qian Feng) and young Mao Zedong (Gu Zhixin) are all people who come to study. Here, they began their five-year campus life.

During his schooling, Mao Zedong gradually became a believer in the theory of saving the country through education. He became a "special student" specially cared for by the school. During this period, Mao Zedong deepened his friendship with Tao Siyong (Shumei Lian) and Yang Kaihui (Qian Fang) in Cai Hesen, Xiao Zisheng and Nan Zhou girls' middle schools. During the turbulent period in China, schools were not spared. A series of events have given these teenagers a new understanding and idea of life, society and the motherland. They are the builders of the future motherland.

Part of the information of the extended material is "just classmates and teenagers"

1. Gu Zhixin plays Mao Zedong.

Mao Zedong eagerly studied his interested knowledge and thinking methods in humanities, social sciences, poetry and writing, and determined to become a believer in non-violent reformism, with the ideal of saving the country through education. But his extraordinary personality and serious eccentricity also made him violate the school rules again and again. When dealing with how to correctly educate and deal with Mao Zedong's deviant behavior, teachers hate iron and don't know how to reach a unified opinion. President Kong, who regards talents as life, finally chose to respect his personality and let it develop-to become a "special student" chartered by the principal.

2. Xu Liang plays Cai Hesen.

In their common study and life, Mao Zedong, Xiao Zisheng and other outstanding young people have forged friendship.

3. Zhao Ran plays Xiang Jingyu.

Because of their common interests, they came together with Mao Zedong and others. They organized and led a book club with their classmates. This reading club has become a link between students' study, communication and emotional development.
