Paul, he is a kind, brave and strong man. He is conscious, selfless, idealistic, ambitious and purposeful, and he has the spirit of devoting himself to the revolutionary cause. He loves reading revolutionary books, which gives him more goals in life. He gave up tonya (Paul's boyhood girlfriend) for the party, which shows that he put the party and the motherland in the first place. Knowing that he was terminally ill, he still didn't give up his life and still wanted to do more for the party. Even if he was lying in his hospital bed, he was writing literature day and night. It shows that Paul is not afraid of death and is willing to sacrifice for the party and the motherland. Paul once said, "Don't regret wasting time, and don't be ashamed of doing nothing." Yes, Paul is very satisfied with his life, because he didn't waste time, because he seized every minute.

The admirable revolutionary Zhu. Very assertive and conscientious. He often teaches Paul boxing, tells him Bolshevik stories, and teaches him to have "the spirit of daring to fight". Paul also became brave and became a soldier because of his "fighting spirit". On another occasion, Zhu was calm when his bayonet was aimed at his back. He is a man who is good at making friends and caring about the group. Without Zhu, Paul, like many people, may not have a strong character and stick to his ideals.

Tonia, a beautiful, witty and considerate woman, was once Paul's beloved. Tonia is also a very active girl. She likes making friends. She took the initiative to make friends with Paul. Paul is willing to jump off the cliff for him. She is the daughter of a rich man, because she and Paul were born in different classes, so she has different ideas. On one occasion, tonya went to attend a meeting of the Youth League. She was beautifully dressed, while everyone else was wearing old clothes. Tonya doesn't like those people either. Finally, let her fall in love with Paul and break up.
