I. Five-character Rhyme
Five-character rhythmic poetry, referred to as five laws for short, is a kind of rhythmic poetry. Five-character and eight-sentence poems that conform to the standard of metrical poems are five-character metrical poems and belong to the category of modern poems. Inherited the basic characteristics of five syllables per sentence, two sentences in the whole text and even total sentences from five-character ancient poems, and added the rules of duality and parallelism; And these rules are borrowed from parallel prose; Parallel prose came into being from Chu Ci to Han Fu; Therefore, the five laws are the product of the grafting of five ancient times.
There are three types of physical metrical poems in Qi and Liang Dynasties: comparison (referring to the metrical form in which all poems are not adhered to each other), adhesion (referring to the metrical form in which all poems are adhered to each other) and mixed rhythm (referring to the metrical form in which all poems are adhered to each other), but comparison is the main one, which is far from perfect modern poetry.
Among them, from the middle and late Liang Dynasty to Chen, there are some works by Yin Keng, Yu Xin, Xu Ling and others. It is very close to the regular poems of the Tang Dynasty. Su Yang, Lu Sidao, Xue Daoheng and others in the Sui Dynasty, combined with the gorgeous ci works in the Southern Dynasty and the fresh and vigorous atmosphere in the northern region, created some beautiful and healthy poems, which pointed out the direction for the development of poetry in the transitional period.
Second, about the leveling of regular poems.
There is a saying about the training of metrical poems: "No matter what 135 is, 246 is clear." This refers to the seven methods (including seven sections). This means that the levels of the first, third and fifth characters can be arbitrary, while the levels of the second, fourth and sixth characters must be different. As for the seventh word, natural requirements are very high. As far as five-character rhyme is concerned, it should be "whether one or three, two or four are distinct."
This formula is very useful for beginners because it is simple and clear. However, its analysis of the problem is not comprehensive, which is easy to cause misunderstanding. This has a great influence. Because it is not comprehensive, we have to criticize it appropriately.
