You can answer this question from three aspects: aesthetic and poetic form and content. The overall impression of the Tang Dynasty is enthusiastic, optimistic and enterprising, and the social environment is inseparable from the Tang Dynasty. Performance poetry is passionate idealism, while romanticism is much more serious. Of course, influenced by Du Fu and Du Fu's poets, they are both concerned about reality and relatively optimistic comrades. But in fact, Du Fu was more positive and optimistic in his early days. Even if he wrote: two on the road, what do you think? Active people. Because it is romantic idealism, I won't say too much poetry and too much Confucian morality with social ideals. This is also a major difference between Tang and Song poetry. Tang poetry emphasizes strong character, which is substantial, rather than moaning meaning and not empty feelings, which began in Chen Ziang. Formal, well, as you said, the organization of metrical poems is completed, and there are too many rhetorical devices and structures, so you can naturally understand them. The contents of realistic poems in Tang Dynasty are landscape poems, frontier poems and farewell poems. Both Du Fu and Li Bai have reached a peak, which can only be surpassed after learning. Your favorite poets in the Tang Dynasty, Li Bai, Du Fu, Wang Wei, Meng Haoran, Gao Shi, Wang Han, Chang Hao, four outstanding poets and four friends, I only quote from the early Tang Dynasty, and I have many in the Tang Dynasty. Probably the sum of the poets in the Tang Dynasty compared with other dynasties we know.
I don't know the characteristics of metrical poetry. One is the number of words, the quatrains of poetry, the final rhyme of each association, and the smooth rhyme of recent poems. This sentence may be pressure, time pressure knows whether this means closing. Then the conjunctions (that is, the last part behind) and the next association of the last word (that is, the first word of the same sentence (that is, the last part before) are glued), and the words connected in the same sentence are relatively different from the first word of the sentence. The requirements of this law run through the whole chapter. This is the most important rule of metrical poetry. Actually, there are many very good places. For example, are those words dull and silent? Of course, it's different now. Without yin and yang, peace is flat, and ascension is silent. With clay, there must be strict laws, accommodation, lack of attachment, loss of rights, gold and salvation. I know so much. Please contact me if you have any questions. I tried to answer.
