In terms of voice, the southern songs are euphemistic and beautiful, while the northern songs are simple and lively. In particular, puns and hidden words are widely used in southern songs, which makes poetry more touching and implicit. Pun argot is mainly composed of homophonic words and polysemy, so there are two situations. The first situation is homonym and homonym: "If there is no coptis, why bother?" "San" is not only the name of medicine, but also the "San" of gathering and dispersing; The taste of coptis chinensis is bitter, which means the bitterness of acacia. The second situation is homonym: such as "lotus" pun "pity", "silk" pun "thinking" and so on, such as "the fog reveals the lotus, but the lotus is not clear" The extensive use of these techniques is not only the infiltration of southern folk customs in poetry, but also adds a bit of liveliness and vividness to poetry. The language of Beige is simple, lively, vigorous and powerful. There is no exquisite diction of Nange, let alone the skill of pun argot.
From the aspect of formal system, most of the folk songs in the Northern and Southern Dynasties are composed of five words and four sentences, which has a great influence on the formation of five-word quatrains, but there are five words, three sentences, five sentences and six sentences in southern songs, which are not found in northern songs; The seven words, two sentences and four sentences in the northern songs are not found in the southern songs.
Finally, the overall style characteristics of folk songs in the Southern and Northern Dynasties are also related to the language characteristics and the emotional characteristics reflected. Southern songs are euphemistic and delicate, while northern songs are bold and straightforward, which is also related to the differences in geographical environment. The southern climate is warm and humid, with dense river networks and rich products, which is easy to cultivate artistic interest characterized by brightness and charm; The north is a Ma Pingchuan, where the landscape lacks detailed changes, and life is relatively simple and severe, but nature is as broad, lofty and vigorous as the south. Such an environment is easy to cast the broad mind and heroic and simple aesthetic characteristics of the people in the north. Therefore, it is also a love song, the southern song is sincere and lingering, and the northern song is bold and crisp.
