The background of the emergence of Shensong School in the early Tang Dynasty

The early Tang Dynasty, from the period of Emperor Gaozong's martial arts to Rui Zongjingyun's period, lasted for about a hundred years, which was the transitional stage of Qi Liang's poetry to the prosperous Tang Dynasty and the preparatory stage for its prosperity. In view of the lessons of the downfall of the rulers in the Southern Dynasties, Emperor Taizong attached importance to the ruling role of ideology and culture and advocated the literary proposition of neutrality and elegance. Most of the works in this period were poems and songs that were ordered to be harmonious between monarch and minister. The main content is to praise, express court life and write scenery praises. Although the language is elegant and the content is empty, after all, Qi Liang's poems have got rid of the shortcomings of lightness and agility, and gradually presented an open and powerful momentum, a lively rhythm and a solemn sense of the universe, which played a positive guiding role in the transformation of poetic style. Some court poets appeared, including Shangguan Yi, Li Qiao, Su Weidao, Cui Rong and Du Fu, who were called "Four Friends of Articles", and Shen Quanqi and Song, who were called "Shen Song". "Shen, Song", mainly in Wuhou and Zhongzong periods. On the basis of summarizing the practical experience of predecessors and contemporaries in the use of metrical poems, they completed "Remembering the illness caused by intonation and observing the sentence accuracy" (a biography of the book of the New Tang Dynasty and the Song Dynasty), which made important contributions to the shaping of metrical poems in terms of flat lines and rhyming sentences. With their meticulous and rigorous creation, these norms are gradually accepted by people. In the early days of Shen Song, many poems were decorated with poems that should have been written for peace, and later they were relegated to remote places. Life experience has brought changes to their creation, and they have written some good poems to express their true feelings. Such as Du Da Yu Ling and Crossing the Han River in Song Dynasty.
