The Silk Road is a commercial and economic route connecting China and Europe. Through it, the communication, exchanges and spreading of trade, cultural and religion between Asia and Europe are more convenient. It is almost 7000 kilometers, separated by the east, middle and west sections, starting from Xi'an in China, passing through Zhangye and Dunhuang, and then divided into three routes to penetrate into the interior of Europe.
The Silk Road began during the period of Emperor Han Wu of the Western Han Dynasty (206 BC-220 AD), Emperor Wu of the Han Dynasty dispatched Zhang Qian to the West Cypriot. Later, the class of the Eastern Han Dynasty exceeded the Western Region, strengthening the relationship between the Western Region and the Mainland. Ban Chao once sent Gan Ying to Rome, extending the Silk Road from West Asia to Europe for the first time. In 166, Roman emissaries also came to Luoyang through the Silk Road, which was the first direct exchange between European countries and China.
