The little girl selling matches is a fairy tale by Danish writer Andersen, which mainly tells the story of a little girl selling matches who froze to death in the street on Christmas Eve when the rich were happy and toasted. On the cold Christmas Eve, there was a little girl selling matches. Because she didn't sell any matches, the little girl didn't eat anything all day.
On the one hand, Andersen himself was born in such a background, so the stories he wrote will bring such tragedies more or less unintentionally.
On the other hand, such a tragedy will encourage people to help more unfortunate people. I read an English expository article, which introduced Andersen's intention of writing fairy tales, "I want to more children live in happy rather than poor or sad" (I want more children to live in happiness, not poverty or sadness).
So, Andersen wrote such a story himself, probably because of the influence of his living environment, but it also achieved his own dream: to make readers feel happy in their lives, and to help unfortunate children who didn't read the story with the help of rich children. Therefore, such a tragedy is not entirely inexplicable. In short, it has achieved Andersen's wish: to make children happy and to make the world a better place.
