Exaggeration is a rhetorical technique
Concretely speaking, it can be divided into three forms. These three types are exaggeration, exaggeration, and advance. In literary creation, we can choose different types of exaggeration according to the situation. The use of exaggeration in literary creation can also inspire readers' imagination to a great extent.
The so-called exaggeration refers to describing objective things as more vast, profound and powerful, etc. Li Bai wrote in "The Difficulty of the Road to Shu", "The Difficulty of the Road to Shu, It is difficult to reach the sky." This sentence is an exaggeration of this form. The opposite of exaggeration is to describe objective things as smaller, thinner, shallower, etc. Advance exaggeration refers to moving the development of things forward in the chronological order, that is, making them happen in advance.
