The Silk Road丝绸之路

The Silk Road was never a single paved highway but a shifting network of caravan tracks and sea lanes spanning some 6,000 kilometres. Its overland heart connected the Chinese capital of Chang'an (modern Xi'an) through the oasis towns of Central Asia to Persia, the Levant, and ultimately Rome. The routes take their modern name from silk, the luxury Chinese textile whose method of production China guarded as a closely held secret.丝绸之路从来不是一条铺好的大道，而是一张不断变动的网络，由商队小径与海上航线交织而成，绵延约6000公里。其陆路的核心，从中国都城长安（今西安）出发，经中亚的绿洲城镇，通往波斯、黎凡特，最终抵达罗马。这些路线的现代名称来自丝绸——这种中国的奢侈织物，其生产工艺曾被中国当作严守的机密。

Regular long-distance exchange opened up under China's Han dynasty. Around 130 BCE the envoy Zhang Qian returned from the western regions with knowledge of distant kingdoms, and the Han pushed westward to secure the trade corridors. From that point silk, lacquerware, and later paper flowed west, while horses, glass, gold, wool, and new crops flowed east.有规模的长途交流，是在中国汉代打开局面的。约公元前130年，使者张骞出使西域归来，带回了对遥远国度的认识，汉朝随之向西经略，以保障贸易通道。自那时起，丝绸、漆器乃至后来的纸张源源西传，而良马、玻璃、黄金、羊毛与新的作物则不断东来。

Goods were only part of the story. The Silk Road was one of history's great highways for ideas. Buddhism travelled from India through Central Asia into China along these routes, carried by monks and merchants and expressed in the great cave-temple complexes such as Dunhuang. Later, Islam, Manichaeism, Nestorian Christianity, technologies, artistic styles, and scientific knowledge all moved along the same paths.货物只是故事的一部分。丝绸之路是历史上思想传播的大动脉之一。佛教沿着这些路线，由僧侣与商人从印度经中亚传入中国，并在敦煌等宏大的石窟寺群中得到表达。此后，伊斯兰教、摩尼教、景教（聂斯脱里派基督教），以及各种技术、艺术风格与科学知识，也都沿着同样的路径传播。

The overland trade reached new heights under the Tang dynasty (618–907), when Chang'an became one of the world's most cosmopolitan cities, and again under the Mongol Empire of the 13th and 14th centuries, whose unified control of Eurasia — the Pax Mongolica — made travel safer. It was in this era that the Venetian Marco Polo famously journeyed east and described the wealth of China to European readers.陆路贸易在唐代（618–907年）攀上新高，当时的长安是世界上最国际化的城市之一；到13、14世纪蒙古帝国时期又再度兴盛——蒙古对欧亚的统一控制（「蒙古和平」）使旅行更加安全。正是在这个时代，威尼斯人马可·波罗东游，并向欧洲读者描绘了中国的富庶。

The overland routes declined from the 15th century, as the Mongol order fragmented and as European powers opened direct maritime routes to Asia, shifting the balance of world trade to the oceans. But the Silk Road's legacy endured: it had knit distant civilizations into a shared, interconnected world long before the modern age, and its exchanges shaped the art, faith, cuisine, and technology of half the planet.陆上路线自15世纪起走向衰落——蒙古秩序瓦解，欧洲列强开辟了直通亚洲的海上航线，世界贸易的重心转向海洋。但丝绸之路的遗产长存：早在近代之前，它就已把遥远的文明编织进一个共享而互联的世界，其间的交流塑造了半个地球的艺术、信仰、饮食与技术。
