Routes
The Han-dynasty Silk Road began at the manigicent capital city of Chang'an ( today's Xian). The route took traders westwards into Gansu Province through Lanzhou, Tianshui, Zhangye, Jiuquan along the Hexi Corridor reached Jiayuguan - the giant barrier of the Great Wall and the first key point of the route- Dunhuang. Dunhuang is in the west end of the Hexi Corridor of Gansu Province. It is one of the well-known Chinese historical and cultural cities, and the bright pearl on the ancient Silk Road.
When the ancient Silk Road came out of the Hexi Corridor into Xinjiang, it broke into three main routes. The southern route ran west along the northern foot of Kunlun Mountains, via Charkhilk ( Ruoqiang), Cherchen ( Quemo), Minfeng ( Niya), and Hetian ( Hotan), then reached Kashgar - another key point on the Silk Road, afterwards went over the Pamirs, and reached India or passed through Afghanistan and Russian Central Asia to reach the coast of the Mediterranean or Arabia. The central route meandered west along the southern foot of the Tianshan Mountains dotted by Loulan, Korla, Chucha, and Aksu, then crossed the Pamirs and led to Mari in Russia. The northern route rambled along the northern foot of the Tianshan Mountains, starting at Hami wound through Turpan, Urumqi, westward reached the Ili River Valley, and led to area as near the Black Sea.
The three routes of the Silk Road ran between mountain ranges and long edges of deserts, going through oases inhabited by ancient tribes. These tribes also opened some branch roads across mountain passes to join the three routes together.
The ancient Silk Road in Xinjiang traversed desolate desert areas and wound over snow-capped peaks. It was full of difficulties and obstacles and more dangerous and fascinating than other sections of the road. It was the only way for China to get in touch with the West between the second century B.C. and the 10th century A.D. Various ancient cultures of the West and East, including some lost cultures, have left traces of themselves in Xinjiang. Although sections of the Silk Road have been buried by sand in deserts, the local dry climate has miraculously preserved sites and relics several thousand years old. Some relics are as good as they were centuries ago.
