The Tang Dynasty, from 618 to 907 A. D., is regarded as the one of the most prosperous dynasties in China’s long history. It was marked by a strong and benevolent rule, successful diplomatic relationships, economic expansion, and a cultural efflorescence of cosmopolitan style.
It was also the golden age of Chinese art and literature. Shi, the classical form of Chinese poetry, developed two thousand years ago in the late Han Dynasty, reached its peak during the Tang Dynasty. Most Tang poems consist of four or eight lines, with five and seven Chinese characters in each line and follow certain regulations.
