1, History: The Silk Road is the product of the monarchies along the route jointly promoting economic and trade development. Zhang Qian made two missions to the western regions 138 years ago-126 years ago and 1 19 years ago, which opened up a new era of communication between China and foreign countries. The Silk Road in a broad sense refers to the long-distance commercial, trade and cultural exchange routes that have been formed since ancient times and spread all over Eurasia, even including North Africa and East Africa.

2. Geographical conditions: The Silk Road usually refers to the commercial road in northern Europe and Asia, which is in contrast with the ancient tea-horse road in the south. In the Western Han Dynasty, Zhang Qian started from Chang 'an, passed through Guanzhong Plain, Hexi Corridor and Tarim Basin, and reached the central region of the Central Asian river between the Syr Darya River and the Uhur River, Great Iran, which was a land passage connecting Mediterranean countries. It is also called the overland Silk Road, because silk products have the greatest influence on the goods transported westward along this road, including South Road and Wuhu River.
