Telling stories illustrates the role of rational writing techniques.

Make the content of the explanation into vivid and interesting stories, so that people can gain scientific knowledge while reading the stories. Most of these stories are anthropomorphic, usually in the third person.

For example, a classmate wrote the story of rosy clouds like this:

Doudou is a common drop of water in the sea. Today, I have a chance to swim to the surface.

"ah! It's so beautiful outside! " Doug can't help but sigh, "Blue sky and white clouds, birds are flying. If only I could go to heaven! " A beam of sunshine shone on her, and she was warm and really comfortable. Gradually, she felt sleepy, her attention became more and more concentrated, and she was no longer interested in seeing the beautiful Tiangong. She fell asleep on her friend. ...

Then, the author tells the story of how Doudou and other small Doudou get together to form white clouds, and when the sun comes out, it becomes rosy clouds. The article begins with the peas rising into the sky and ends with their return to the sea, explaining the formation, swimming and beautiful colors of rosy clouds in turn. The plot is very vivid and imaginative.
