Metaphor is metaphor, which can be divided into simile, metaphor, metonymy, duality and contrast. The use of metaphor can highlight the characteristics of things, make the expression more vivid, and turn abstruse abstraction into simplicity and concreteness. Such as: the water level in a rain pond, gently grinding the mirror to look at the eaves.
Personification is to write things as adults, and using personification can make the colors bright, portray the image and convey the meaning. For example, "the geese lead the heart to worry, and the mountains hold the moon."
Exaggeration is a rhetorical device that deliberately enlarges or narrows the image, characteristics, function and degree of things in order to achieve a certain effect. Using exaggeration can reveal the essence, contrast the atmosphere and enhance association. For example, "Flying down three thousands of feet, it is suspected that the Milky Way has fallen for nine days."
Using contrast, we can distinguish different characters, different life phenomena and different thoughts and feelings more clearly. For example, "Pipa dance has a new sound, always closing the mountain and keeping old feelings." I can't listen to endless worries, and the high autumn moon shines on the Great Wall.
