A: Chapter 3 of Part II of How Steel was Tempered.

Paul Kochakin's famous words about life:

Life is the most precious thing for people. Everyone has only one life. A man's life should be spent like this: looking back, he will not regret wasting his time, nor will he be ashamed of his meanness and vulgarity; On his deathbed, he can say, "My life and all my energy have been devoted to the most magnificent cause in the world-the struggle for the liberation of all mankind."

What Paul said when he visited the grave of his female comrade-in-arms Eva Lian. The following is taken from the cemetery in Chapter 3, Part II of How Steel was Tempered:

Paul unconsciously approached the pine forest and stopped at the fork in the road. On the right is the gloomy old prison, which is separated from the pine forest by a high pointed wooden fence. Behind the prison is the white building of the hospital

It was here, in this empty square, that Valia and her comrades were hanged. Paul stood silently for a moment where the gallows were first laid, and then walked down the steep slope to the cemetery where the martyrs were buried.

I don't know who put a wreath made of spruce branches around the grave, like building a green wall for this small cemetery. Tall and straight pine trees stand high on the steep slope, and the hillside of the canyon is covered with green grass.

This is the edge of the town, quiet and deserted. The pine forest is whispering, the spring of the earth is reviving, and it smells damp and earthy. Comrades died heroically here. They gave their lives for those who were born in poverty and became slaves in order to live a better life.

Paul took off his hat slowly. Sadness, great sadness, filled his heart.

Life is the most precious thing for people. Everyone has only one life. A man's life should be spent like this: looking back, he will not regret wasting his time, nor will he be ashamed of his meanness and vulgarity; On his deathbed, he can say, "My life and all my energy have been devoted to the most magnificent cause in the world-the struggle for the liberation of all mankind." Seize the time and live quickly, because an inexplicable disease or an unexpected tragic event will interrupt life.

With this in mind, Paul left the tomb of the martyrs.
