The difference between literary vulgarity and elegance

The vulgarity and elegance of literature are most simply embodied in poetry, in which vulgarity is vulgarity, such as doggerel, Song Ci and Yuan Qu, and elegance is elegance, which is derived from the title in the Book of Songs. At first, it refers to praising the good politics of ancient times and the former dynasties and offering sacrifices to the memory of the court party & feudal morality, and then it is widely spread to sing praises, belittle the disadvantages of the times and miss historical sites. Vulgarity and elegance are almost the same, but they show more local language characteristics, integrate local culture and literature, and express more trivial things of people's lives (such as labor, homesickness, marriage feelings, etc.). ), but also vulgar, let more people come into contact with literature.
