What greatly improves the use value of poetry?

"Jinshi is selected based on poems and poems" which greatly improves the use value of poetry.

Detailed analysis: Xu Song, a scholar of the Qing Dynasty, said in the book "Deng Ke Ji Kao" which examines the imperial examination system of the Tang Dynasty: "According to two essays, namely proverbs, inscriptions, treatises, tables and the like, Fu began to be written in the Kaiyuan period One of them is poetry, and there are also those who use poetry exclusively, not custom-made poetry. The special poetry for essays should be among Tianbao." He believed that the use of poetry to recruit scholars began in the reign of Emperor Xuanzong of the Tang Dynasty. . At that time, there were three examinations for Jinshi. The first one was about poetry and poetry. Those who failed were exempted from the next two examinations. According to historical records, during the reign of Emperor Xuanzong, examinations based on poems and poems were held in the first, second, fourth, fifth, seventh, eleventh, twelfth, fourteenth, fifteenth, eighteenth, and second years of Kaiyuan. Several times in the tenth, twenty-fifth, twenty-sixth and Tianbao years, quite frequently, and later became customized. Many famous lines appeared in the provincial examination poems of the Tang Dynasty, such as "Looking at the remaining snow in Zhongnan Mountain" written by Zu Yong, "The Yin ridge in Zhongnan is beautiful, and the snow is floating in the clouds. The forest shows the color of Ji, and the city becomes colder at dusk"; Qian Qi "At the end of the song, no one can be seen, and the peaks on the river are clear" are among the outstanding ones. More importantly, due to the implementation of the examination method of selecting poems and poems, a large number of scholar-officials devoted themselves to studying poems and poems, which greatly promoted the development of literature in the Tang Dynasty.
