is one of the basic forms of metrical verse, and it is a requirement for the leveling of Chinese characters in a metrical poem. Seven-character metrical poems (including metrical poems and quatrains) have four basic sentence patterns, and this is one of them.
There are four basic sentence patterns in metrical poems, namely:
1. Flat and flat: flat and flat; Such as: Gushan Temple North Jiating West.
2, flat and flat: flat and flat; Such as: leaves are dropping down like the spray of a waterfall.
3. flat collection: flat collection; Such as: while I watch the long river always rolling on.
4. collect from the beginning: average. Such as: stuffed with autumn wind and sad horses.

The requirements of metrical poetry for flat tones
Although Chinese has four tones, in metrical poetry, it is not necessary to distinguish four tones like words and songs, as long as they are roughly divided into flat tones. To cause cadence in tone, it is necessary to use flat voice and flat voice alternately, so as not to be monotonous. Chinese basically takes two syllables as a rhythm sheet, and the stress falls on the later syllables. The basic sentence pattern of metrical poetry is composed of two syllables, which is called metrical sentence.
there are four basic sentence patterns in the five-character rhyme: (a) flat and even, (b) flat and even, (c) flat and even, and (d) flat and even. Seven-character verse only adds a rhythm unit before the five-character sentence pattern, and its basic sentence pattern is: (a) flat and flat, (b) flat and flat, and (c) flat and flat.
There is a rule in these sentence patterns, that is, every pair will be reversed: the level of the fourth word is opposite to the second word, and the sixth word is opposite to the fourth word, thus forming a sense of rhythm. However, every single word can be reversed, because the stress falls on even syllables, and the singular syllables are relatively unimportant.
Therefore, there is a formula of "No matter one, three, five, two, four and six are distinct", which means that the level of the first, three and five words (only seven words) can be handled flexibly, while the level of the second, four, six and the last word must be strictly observed. This formula is not completely accurate. In some cases, one, three and five must be discussed, and in certain sentence patterns, two, four and six may not be ignored, so they should be treated differently.
