What is an elaborate narrative?

This writing technique is actually the "Fu" in the Book of Songs "Fu, Bi and Xing".

For example, the following fragment is the elaborate narrative in the poem, which is "Fu":

For example, in Peacock Flying Southeast,

The cock crows and the bride wears strict makeup. Embroidering my skirt, everything is four or five. My feet are tiptoeing and my head is shining. If the waist is flowing, you will hear the bright moon. Refers to the root of onion, and the mouth contains Dani. Fine steps are unparalleled in the world. Worship my mother in class, and she is angry.

This paragraph describes the beauty of Liu Lanzhi, which is just an elaborate narrative. The next paragraph is also:

Now that you are twenty-seven, you can go and get married. Pay attention to the speed of speech, such as floating clouds. Green finch and white stork boat, four-cornered dragon. Graceful with the wind, golden car jade as a wheel. Wandering green horses with tassels and gold saddles. The money is 3 million, all of which are worn with moss. 3 horses with mixed colors, and the salmon in Jiaoguang City is precious. From four or five hundred people, Yu Yudeng County Gate.
