The most impressive thing about Andersen is the short article about a drop of sewage, which is said to be a swath of bacteria in the sewage, but it is only a drop in a puddle of sewage, and the sewage will eventually flow to the ocean. His fairy tales are basically tragic endings. When I was a child, I didn't like Andersen's fairy tales, but I liked to listen to the happy Grimm fairy tales of the princess and the prince. After growing up, I slowly understood the foam of light on the sea.
