the ancient city of jiaohe is located in the yarnaz valley, 13 kilometers (8 miles) west of turpan, and was once the capital of the state of south cheshi, which was one of the 31 states in the western region of china. base on historical book records "the state of south cheshi made jiaohe city as its capital, as it was strategically seat on the confluence of two rivers, hence the name 'jiaohe' (the city of joining rivers)." shielded by natural cliffs, the city was built on a 30-meter- (98-foot-) high loess plateau, with a measurement of 1,650 meters (5,414 feet) long and 300 meters (984 feet) wide.
during the western han dynasty, "jiaohebi" (an administrative division) was established and continues through from the period of northern wei to the early tang dynasty. later it became jiaohe prefecture under the jurisdiction of huigu gaochang kingdom. the anxi military viceroy's office, which is the highest civil and military administrative organ in the western region, was set up here. between the middle of the eighth and the ninth centuries, the tibetans occupied the city. at the end of the thirteenth century, it was destroyed in a mongolian aristocratic rebellion.
