What did Chinese poetry during the Tang Dynasty celebrate?

Chinese poetry during the Tang Dynasty means Chinese poetry in its most splendour. During the Tang Dynasty which stretches from AD 618 to 907, not only Buddhism reached its peak but Christianity also arrived in China. Therefore the influence of Buddhism, Christianity and Taoism cannot be denied in Tang Dynasty poetry. The greatest poems in Chinese literature were created during this time. The thread of sorrow that underlines the poetry of this time was derived from Buddhist influence on literature. And so were the images of heaven and hell. The prosperity and splendour in the Tang dynasty liberated poets and generated lavish free time for them to write poetry. But not all poets were rich or officially employed; many of them were poor. Tang Dynasty added beauty of diction and perfection in form and style to Chinese poetry which already had been endowed with richness in plot and length. The originality and completeness of these additions were what determined the genius in Chinese poetry. Their four centuries' consecutive addition of folk music and dance music made Chinese poetry diverse in variety and uniquely musical. Chinese poetry became wonderful with this addition of war, disaster, friendship, nature's beauty, meeting and farewell of friends, moonlighting of concubines, wine, and birds' cooing and moonlight into their themes. The life of the poets of this time was also diverse as were the plot and theme and music in their poems. Li- Po, that drunkard who was a member of 'The Six Lazy In The Reed River' who lived in mountains and sent listeners to dream lands through poems lived and died poor. Tu-Fu, who also was a courtier like Li-Po but lacked the sweetness of Li Po and his boldness to experiment with poetry, cleansed the minds of readers and listeners through his heart-melting poems of grief. He also lived very poor and some of his children even died of poverty. Po-Chu-Yi, that Confucian scholar who was lucky to have a government employment, thrilled the people of China through his very popular romantic poems. The soldier Chen-Tsu-Ang, military advisor Sung-Chizh-Van and painter Wang-Wei were a few of the other poets of this time whose poems included in the 'Collection of 50,000 Poems' is still being read. Printing also was introduced during the Tang Dynasty. It must also be remembered that the oldest print book was from 868, discovered in a cave temple in Tun-Huang.
