The ancients divided the pronunciation of Chinese characters into four tones, namely, ping, Shang, Jin and Qu (in which ping is divided into Yin Ping and Yang Ping). Because Latin is not expressed by vowels as it is now, the ancients chose a word from each word with the same vowel to use as a vowel.

Ancient poetry is the general name of China's ancient poetry, which refers to 1840 China's poems before the Opium War. From the perspective of meter, ancient poetry can be divided into ancient poetry and modern poetry. Taking the Tang Dynasty as the boundary, the previous poems were all ancient poems, and later, the ancient poems gradually declined and died out. Ancient poetry is also called ancient poetry or ancient style; Modern poetry is also called modern poetry. From the Book of Songs to Yu Xin in the Southern and Northern Dynasties, they are all ancient poems, but the poems after the Tang Dynasty are not necessarily modern poems, but they are distinguished according to rhyme.
The number of words and lines in classical poetry;
Classical poetry has a fixed verse and a fixed style. All ancient poems are classified according to the number of words in the poem. Four-character ancient poems are referred to as four-character ancient poems for short; Five-character ancient poems are referred to as five-character ancient poems for short; Seven-character ancient poems are referred to as seven-character ancient poems for short. Four-character poems were adopted by people as early as the Book of Songs. But it gradually declined in the Tang Dynasty, and few people wrote it. Therefore, ancient poetry is still expressed in five words and seven words.
Five-character ancient poetry is the orthodoxy of ancient poetry, and many people write it.
Seven-character ancient poetry is not the mainstream of classical poetry, because it originated late. Therefore, the seven-character style is greatly influenced by the seven-character modern poetry.
Five-character ancient poems and seven-character ancient poems are both ancient poems with neat words. There is also a kind of ancient poetry with mixed words, and the length between the lines is different and uneven.
