Paul Kochakin, born in a poor railway worker's family, lost his father in his early years and made a living entirely by his mother washing and cooking for others. /kloc-when he was 0/2 years old, his mother sent him to the station canteen to do odd jobs and was humiliated there. He hates bullying shopkeepers. He hates rich people who spend their time drinking.

After the "October Revolution" broke out, imperialists and reactionaries attempted to strangle the nascent Soviet regime. Paul's hometown, Shebetoka, Ukraine, has also experienced years of foreign armed intervention and civil war. The Red Army liberated the town of Shebetovka, but it quickly retreated, leaving only the old Bush Viktojuk to do underground work in the town. He stayed at Paul's house for a few days and told him a lot about the revolution, the working class and class struggle. Zhu was the initial leader of Paolo on the revolutionary road.

On a fishing trip, Paul met tonya, the daughter of a forestry official.

One day, Zhu was captured by the white bandit troops. Paul inquired about his whereabouts everywhere. On the way of the bandit troops escorting Zhu, Paul swooped down, knocked the bandit troops down in the trench and escaped with Zhu. Paul was sent to prison because of the snitch of Victor, the son of Polish aristocrat Lizensky. In prison, Paul endured torture and was strong and unyielding. In order to welcome Bai Fei leader Petriu to visit the town, a second-class officer mistakenly released Paul as an ordinary prisoner. Afraid of falling into the clutches again, he didn't dare to go home, so he involuntarily came to the front of tonya's garden and jumped into it. Because Paul saved Niya on his last fishing trip, and she liked his "passionate and stubborn" personality, so her arrival made her very happy. Paul also thinks that tonya is different from other rich girls. They all feel hazy love. In order to take refuge, he agreed to tonya's request and stayed. A few days later, tonya found Paul's brother Arqing, and he sent his brother to Khartoum to join the Red Army.

Paul worked as a scout after joining the army and later became a cavalry. He is an able man who dares to charge on the battlefield and an excellent political propagandist. He especially likes reading Gadfly, Spartacus and other works, and often reads aloud or tells stories to his comrades. In a fierce battle, his head was badly injured, but he overcame his death with tenacious perseverance. His physical condition prevented him from returning to the front, so he immediately devoted himself to restoring and building the country. He worked in the league, eliminated counter-revolutionaries and devoted himself to hard manual labor. In particular, the work of building railways is particularly difficult; Autumn rain, mud, heavy snow, frozen soil, lack of clothes and food, open-air accommodation, but also attacked by armed bandits and threatened by disease.

During this period, his love with tonya was in crisis, and tonya's vulgar individualism disgusted him. When I saw her again when I was building the railway, she had married a rich engineer. When Paul was the secretary of the Youth League Committee in the railway factory, he had frequent contact with Lida, a member of the Youth League Committee, and they gradually developed feelings. But he mistook Rita's brother for her lover and lost the chance to fall in love with her.

At the end of the road construction work, Paul got typhoid fever and caused pneumonia, so the organization had to send Paul back to his hometown to recuperate. On the way, he falsely reported that Paul was dead, but Paul defeated death for the fourth time and returned to the world. After his illness, he returned to work and joined the party. Due to various injuries and selfless work, Paul's physique is getting worse and worse, and he has lost his ability to work. The party organization had to terminate his work and let him stay in hospital for a long time. While recuperating at the seaside, he met Daya and fell in love. While constantly helping Daya to make progress, Paul began to study tenaciously and improve his writing ability. 1927, Paul was completely paralyzed and then became blind. The raging disease finally bound the soldier full of fighting passion to the hospital bed. Paul once had suicidal thoughts, but he soon got out of the trough. This paralyzed, blind man with no writing experience began his heroic career-literary creation. Paul endured great physical and mental pain. First he wrote in a cardboard box, then he dictated it himself and asked someone to record it for him. With the help of his mother and wife, his novel How Steel was Tempered was finally published in 1934! Paul took up new weapons and started a new life.
