Changes

The '''Tang dynasty''' ruled [[China]] for three centuries, from A.D. 618 to 907. This is known as the golden age of art and poetry. New territories were acquired, including [[Manchuria]], [[Tibet]], and northern [[Vietnam]]. This territory drew wealth from surrounding states through a ritualistic ''kowtow'', such that diplomats from surrounding states were expected to pay homage to the emperor by touching their forehead repeatedly to the ground beneath the emperor. The Tang dynasty accumulated vast wealth for China during this period.

Many roads were built at that time, along with inns, post offices and stables for the horses of travelers. The roads were used for trade and communication in a manner similar to the [[Persian Royal Road]] and the roads of the [[Roman empire]].  Foreign music, religion ([[Buddhism]], primarily), clothes and even languages became popular in China at this time.  Importantly, everything in the big cities of China at this time was somewhat state-controlled; curfews were imposed on the citizens, trade was conducted in government approved situations, using government-approved measures and weights.
