What stages did Paul go through in his growth?

"How steel is tempered" Paul's four growth stages and descriptions are as follows:

Paul's life has four stages, from childhood to joining the Red Army, which is the first stage of his life.

At this stage, Paul "caught a glimpse of the bottom of life, caught a glimpse of sediment and dregs, and smelled the smell of decay". In the Red Army, defending the Soviet regime with blood and life is the second stage of Paul's life experience.

He and his comrades-in-arms "whipped up their horses", severely cracked down on aggressors and counter-revolutionaries and traveled all over the country. Participating in the recovery and construction of the national economy is his third stage.

What saddens him most is the fourth stage of losing his health. His right leg is disabled and he is blind. The most painful thing is that he is far away from the job he loves. He even thought about suicide, but he survived and used literature as a weapon to "return to the team and start a new life."

How the Steel was Tempered successfully shaped Paul. Kochakin, a young hero, is closely related to the fate and development of the country and the nation, and is full of positive energy, which is exactly what we should pay attention to.

In the process of reading, we should sort out four stages of Paul's growth: "Paul in his youth", "Paul in the war", "Paul who devoted himself to the construction of his homeland" and "Paul who is disabled and determined". Analyze the image characteristics of Paul in each stage, and then synthesize them to understand Paul's heroic image as a whole.
