The first is visualization. The proper use of reduplicated words in poetry can make the natural scenery or characters described more vivid. In Nineteen Ancient Poems, six groups of overlapping words are used in the first six sentences of "grass on the green side": "grass on the green side, willow in the lush garden. Yingying is a woman upstairs with eyes as bright as windows. E-E red makeup, delicate hands. " The first two sentences describe the scenery, using "green" and "gloomy" to describe the vitality of dense vegetation in spring; The last four sentences are written about people, and the four sets of overlapping words describe the posture, appearance and dress of the thinking woman very realistically, almost vividly.
The second is accuracy. Overlapping can imitate sound and color, achieve the rhetorical effect of description and make the image expressed more accurate. For example, in Poems for Jiao Zhongqing's Wife, "The official horse is in front, the bride's car is behind, and there is a faint hall, and the entrance of Huida Road", using "faint" and "temple hall" to imitate the sound of horses and chariots is very accurate, rendering the sad atmosphere when Lan Zhi was sent home, giving people a heavy feeling. Overlapping can also imitate various sounds; In Du Fu's Ascending the Mountain, "leaves fall like the spray of a waterfall" uses "rustling" to imitate the sound of fallen leaves; In Huang Chao's title chrysanthemum, "autumn wind plants all over the courtyard", imitating the wind with "rustling"; In Yue Fei's "Man Jiang Hong", "On the railing, it's raining and resting", and the sound of rain is imitating "It's raining" ... When the words are superimposed for marriage, it reads: "The matchmaker gets out of bed, Nuo Nuo Fuer." Here, "Nuo Nuo" and "Er" are promises, which are equivalent to the words "good, good" and "just like this" in modern Chinese. These two groups of overlapping words vividly describe the matchmaker's flattering character. Another example is "Mulan Ci", and it is also very accurate to write Mulan's sigh with the refrain of "chirp after chirp".
The third is musicality. Reduplication can make poetry rhythm harmonious and catchy to read; That sounds sweet. For example, Li Bai's "The Tenth of the Seventeen Qiupu Songs": "There are ten thousand Ligustrum lucidum trees in Qian Qian. Egrets in the mountains, white apes in the streams. Don't go to Qiupu, the sound of apes will hurt the guest's heart. " The first four sentences of the poem are led by reduplicated words, which are lively and full of musical beauty.
The fourth is strengthening. Reduplication is easier to read and plays an emphasis role.
