in the early 194s, Hemingway came to China to report on War of Resistance against Japanese Aggression. From 1942 to 1944, he was commended for patrolling the sea with the yacht "pilar" (a warship converted into an anti-submarine at the expense of the government). He led a guerrilla group to fight for the liberation of Paris, so he was accused of violating the Geneva convention's stipulation that journalists should not take part in the fighting. Hemingway appeared in court and was acquitted, and later won a bronze medal.

Hemingway published the novel Crossing the River into the Forest (195) and the novella The Old Man and the Sea (1952) in the 195s. The theme of The Old Man and the Sea is that people should face failure bravely. There is a famous saying in the novel: "A man is not born to be defeated. You can destroy him as much as you can, but you can't beat him." The image of the hero fighting alone is the continuation and development of Hemingway's "tough guy character" created in the 192s and 193s. Its artistic generalization is higher, reaching the height of fable and symbol. The Old Man and the Sea won the Pulitzer Prize in 1952.
