"How Steel is Tempered".

According to Sina query, the Soviet writer Ostrovsky wrote in "How Steel Was Tempered": "The most precious thing for a person is life. Life is the most important thing to a person." There is only one time in a person's life that he should spend his life like this. When he recalls the past, he will not regret wasting his time, nor will he be ashamed of doing nothing. This sentence also reflects human beings' understanding and cherishment of the essence of life, and emphasizes the importance of life. Uniqueness and irreversibility remind people to cherish life, actively face challenges and difficulties in life, and strive to realize their own value and meaning.
