Silk Road (Volume Name: Textiles)
the Silk Road
Ancient trade routes across the Asian continent. From the 2nd century BC to the 9th century AD, Chinese and foreign trade, mainly silk, was very frequent. The trade through this channel has promoted the cultural exchange between the East and the West and the economic prosperity along the way, especially the westward spread of sericulture and silk technology in China. /kloc-At the end of 0/9, German geographer Richthofen first used the name "Silk Road". Later, a large number of cultural relics such as silk from the Han and Tang Dynasties in China were unearthed in this passage (see Silk History in China and Textile Cultural Relics in China). In the 2nd century BC, Emperor Wu of the Han Dynasty sent Zhang Qian and others to the Western Regions with valuables such as silk, which opened the way for China to reach Central Asia and then the Mediterranean. After the Song Dynasty, most of China's foreign trade changed to sea, and the "Silk Road" gradually lost its former importance.
The "Silk Road" route is not completely fixed, nor is it one. Among them, the route from southwest Kashgar to India, West Asia and even Europe is the most important. Kashgar was called Shule in ancient times, and it was called "Silk Market" according to the local meaning.
During the Han Dynasty, China, West Asia and Europe had not mastered the technology of sericulture and silk harvesting. Not only a large number of China silks were trafficked through the Silk Road, but also a large number of silks were transported to the West as raw materials for silk fabrics. In the 2nd and 3rd centuries, sericulture technology spread to Hotan, Xinjiang. A drawing board was left at Wuyuleke site, on which the story of the introduction of silkworm eggs was written. There were mulberry trees (dead) at the Minfeng site. According to Tibet's "History of Khotan", sericulture technology in the Central Plains once spread to present-day Kashmir. In the 4th century, China's sericulture technology was introduced to India through the Silk Road. In the 6th century, Persia sent envoys to China along the Silk Road to learn silk technology. Later, China's sericulture technology spread to Byzantium and Arabia, and it was more expensive for Rome and Byzantium to take China's silk. There are many kinds of silk fabrics unearthed along the "Silk Road" in Han and Tang Dynasties, and they are beautifully woven. The weave and pattern of silk have a great influence on silk weaving production all over the world. Gao Hanyu Ding Xinxin
