Is Chenzhou the back garden of Hunan?

Metaphorical sentence is a common rhetorical device, which means to replace abstract and difficult things with simple, concrete and vivid things. The basic structure of figurative sentences is divided into three parts: ontology (figurative object), figurative words (words expressing figurative relationship) and figurative body (figurative object).

1. The two things are somewhat similar. When using metaphor, we should first make clear what features we want to express, and then actively carry out association and imagination according to this feature to find something similar to the ontology but completely different. If there is no similarity, it is not a metaphor. For example, a student wrote her classmate in her composition: "She smiled so sweetly, like a cantaloupe." This classmate didn't understand the different meanings of "sweet". "Smiling sweetly" means that the facial expression is well stretched, not sweet in taste, which is not quite like "cantaloupe", so I made a joke. 2. Easy-to-understand, appropriate and vivid metaphors should be familiar to most readers and listeners, and should be adapted to the ontology, so as to arouse the imagination and interest of readers and listeners. The allusion of "salt sprinkling in the air can be simulated, and catkins are not caused by the wind" illustrates this truth. The same composition is titled "What a heavy snow", and it is more appropriate for some students to write "I stepped on this white sponge gently". Another student compared snow to "frozen tofu", which is not appropriate enough. Another student wrote that "everything is white, just like a war, and every position is occupied by snow", which is even more inappropriate.
