Were China a tree, Beijing would be the crown while Xian would be its deep roots. Xi'an, formerly known as Chang'an, is the oldest of the Four Great Ancient Capitals of China.
“Chang’an’s broad avenues link up with narrow lanes, where one sees Black oxen and white horses, coaches made of seven fragrant woods. The emperor’s jade-fit palanquin sweeps past the mansions of princesses, Gold riding whips in an unending train point toward marquises’ homes. The dragon biting the jeweled canopy catches the morning sun, The phoenix disgorging dangling fringes is draped with evening’s red clouds.”
