The author used three exclamation points in succession. The first exclamation point expresses surprise and admiration for Huang Jiguang's coming forward. The last two exclamation points highlight how great it was for Huang Jiguang to stand up under the enemy's bullets when he was seriously injured, and praise Huang Jiguang's tenacious will and patriotism.

Exclamation marks mainly have the following functions: to indicate the pause at the end of an exclamatory sentence, and also to be used in imperative sentences with strong tone and after rhetorical questions with strong tone. Exclamation marks can be used in simple sentences with strong tone, non-subject-predicate sentences and exclamation marks with strong feelings, and can also be used at the end of slogans and slogans, if feelings are strong.
