Most of the ancient poems before the prosperous Tang Dynasty were ancient, with no strict word limit and flexible rhymes, which were suitable for expressing feelings.
Modern poetry appeared a long time ago, but it was not standardized. It was not until the prosperous Tang Dynasty that strict norms were formed. According to the genre, it is divided into metrical poems and quatrains, and according to the number of words, it is divided into seven words and five words. There are strict requirements on the number of words, the level and the rhyme.
Modern poetry has been popular since the Republic of China.
