From the linguistic point of view, the language of couplets is neither a verse language nor a prose language, but a special language that pursues antithesis and is full of musicality. The special "language structure" of couplets is completely determined by the special nature of Chinese and its characters. The uniqueness of this "language structure" makes the creation of couplets different from other literary forms in conception, conception, layout and writing. With the same objective object and content, we always try to observe and describe things from two aspects and angles, and strive to "shape" the language into a binary and symmetrical structure.
On the other hand, couplets are extremely inclusive. It can combine the characteristics of other styles, absorb the expressive techniques of other styles, especially long couplet and super-long couplet, and simply combine the achievements of Chinese stylistic techniques. For example, the refined meaning of poetry, the exaggeration of fu, the long tone of words, the significance of songs, the free and easy prose, the short rhyme of scriptures, etc., are all eclectic and innovative.
