Poetry before the Tang Dynasty came directly from life and reflected life. For example, plants were born in the soil and let it be natural, so they grew. In the Tang dynasty, the ideological atmosphere was active, and poems were lyrical, uncut, and came out casually. This was the bearing of the Tang dynasty, so it was called shouting; Song people are confined to Neo-Confucianism, and poetry seeks to reflect Neo-Confucianism, so they think; After the Song Dynasty, the culture became increasingly autocratic, and scholars mostly buried themselves in old paper piles and seldom reflected their true thoughts, so it was called imitation. Of course, this just means that the general style is different. For example, Tang poetry wins by meteorology, while Song poetry wins by learning. Can't be absolute. Because from the creative point of view, many Tang poems are also fabricated. There are many poets in the prosperous Tang Dynasty in Heroes of Crossing the River. After all, there are only a few people who can really write like gods.
Reading the poems of Meng, She Jiangcai, Furong and Guiyuan, compared with the poems of later generations, we can better appreciate the lasting charm in emotion and language style.
