The Tang Dynasty, which dated from 618 and ended in 907, was the most prosperous period in Chinese history. After nearly three hundred years of development, it had become the most flourishing power around the world, with its capital Chang’ an as the largest metropolis in the world. China during that period was embodied in the booming economy, thriving commerce, stable social order and even the open borders. As urbanization gained its momentum and wealth accumulated, art and literature also flourished. Li Bai and Du Fu were poets distinguished for their concise and natural writing style. Their poetry struck a chord with scholars as well as ordinary people. Even today, many of their poems are still widely read and recited by children and adults.
