Our teacher said the answer today, I hope it will help you. Signboards are meant to be hung in front of shops as signs. The "signboard" here is an image metaphor, comparing the cloud to the "signboard" of the weather. People can infer what the weather will be like in the future through various changes of clouds. So clouds are like a sign of the weather. (Metaphor means analogy. )

Interpretation of "signboard" in Zhu Yongxi's "Seeing the weather from the clouds": ontology: cloud; Vehicle: signboard. Similarities: Both of them have indication function. But the signboard is more obvious, close to life and easy to understand. Therefore, the signboard is used as a metaphor, which is vivid. The word "signboard" is figurative here. The original meaning refers to the sign hanging in front of the store to indicate the name of the store or the goods sold. As a symbol of the store, it is used here to vividly illustrate the close relationship between clouds and weather. The appearance of clouds is closely related to the change of weather. By observing different forms of clouds in the sky, we can know what kind of weather will be there.
