First of all, if it is a metrical poem, the second sentence, the third sentence, the fourth sentence and the fifth sentence must be antithetical sentences, such as Gong in the Wind and General Hunting the Acropolis. The grass is yellow in autumn, and the eagle eye is sharper; When the ice and snow melt, the horseshoe is extraordinarily brisk. It has passed Xinfeng City in a blink of an eye and soon returned to sunny Liu Ying. Looking back at the eagle wilderness, thousands of twilight clouds spread to the horizon.
This is not the most important thing, because there are sometimes antitheses in ancient styles, and there are not necessarily antitheses in quatrains. But the following points are inevitable: when famous writers write ancient prose, in order to distinguish it from regular sentences, they usually deliberately leave three tones, that is, three flat tails. For example, the word "melancholy" in "Today has hurt my heart more" is flat, which is a rather awkward sentence in legal sentences, but in order to show that it is antique, the author will deliberately write it like this. Another example is Li Bai's "Guan Shanyue": the bright moon rises from the mountain of heaven, and in the boundless haze of the sea of clouds, it is an ancient style at first. Another example is Li Bai's cart.
Among the famous poets, Li Bai wrote a lot of ancient styles, which may be related to his bold and unconstrained poetic style.
In view of the statement on the first floor, many of my mouths and sentences are not necessarily five words and seven words. Li Bai himself has written many six-character poems, which are very fresh and leisurely. Of course, the six-character poem also has a meter, that is, one word is removed from the seven-character poem, and the other requirements for leveling remain unchanged.
Generally speaking, as long as you see three tones in a poem, that is, the ends of three flat tones (the first and second tones in modern Chinese), it means that the author deliberately left three flat tails, which means that he wrote ancient style. This is the easiest way to distinguish ancient poetry from modern poetry.
Keyboard code words are not easy to copy and paste, hope to adopt them.
