Comparison is a kind of analogy. Comparing one thing with another, the poet has skill or emotion and uses one thing as a metaphor.
Xing is touching things to stimulate words, and objective things trigger poets' emotions and cause poets to sing, so it is often at the beginning of poems.
1745 narrative poem Peacock flies southeast, except for the first two sentences, "Peacock flies southeast and drifts five miles", the rest uses the method of "Xing". It is used to arouse Liu Lanzhi and Jiao Zhongqing's love for each other and decorate the atmosphere of the whole article.
In the last paragraph, in the cemetery where Liu Hejiao was buried together, the branches and leaves of pine, cypress and phoenix trees were hidden, and Yuanyang sang all night. This not only symbolizes the immortality of Jiao Liu and his wife, but also symbolizes their eternal grief and accusation. From the realistic double-burial portrait to the portrait of a pine, cypress and mandarin duck symbolizing eternal love and happiness, it shows the people's belief that freedom and happiness will inevitably come in the future. This is the romantic development of Liu Jiao's image, shining with incomparable ideal brilliance, which makes the whole poem have a qualitative leap.
The whole article adopts the style of "Fu", which is vivid and superb.
I remember when I studied this text, that is to say, the first sentence is "Qi Xing". I can't say that all other sentences are separated. There are three ways to promote Fu Bi.
