In A Farewell to Arms, Hemingway takes his personal experience in the war as the creative basis, and Henry, a boy, as the development clue of the work. With Henry's help, Hemingway expresses his distinctive theme-war-weariness and anti-war thought to the world.

A Farewell to Arms shows Hemingway's artistic achievements. His unique creative style is composed of the description of the environment in which scenes blend, the expression of emotions with pure actions and images, the dialogue in the form of telegrams, the simple and true inner monologue satirizing intentionally or unintentionally, the simple and refined style and the tempered everyday language. It has also become a masterpiece of modern world literature.
