The essay Pingyao Ancient City uses metaphor and personification.

Parallelism: Summer is the season of sports. Look, some people are playing ball, some are playing chess, and some are running. Life lies in exercise.

Metaphor: The weather in summer is really changeable. One minute it cleared up, and then it rained cats and dogs in the blink of an eye. For farmers who are catching up with the sun and drying their millet, summer is really an eccentric child.

Personification: cicada asks summer: Have you ever heard someone complain that the weather is too hot in summer? After listening to this, the dark clouds in summer came at once, the sky was overcast at once, and it rained heavily soon. It turns out that summer is considerate.
