汉武帝时代开疆拓土和对外交往的辉煌功业,开创了中外交通与交流的新局面。从此中外交往不断扩大,造成了周边民族和域外国家的内属和入贡,同时带来了大量异域物产的输入。文化交流是通过不同途径实现的,古代交流的主要途径有使节往来、贸易活动、宗教传播、战争俘掠和民间交流等。 During the reign of Emperor Wu of Han Dynasty, the splendid career of pioneering the territory and dealing with foreign countries opened up a new phase of traffic and exchange between China and foreign countries. Since then, the continuous expansion of exchanges between China and foreign countries has resulted in the infiltration and tribute of the neighboring ethnic groups and extra-territorial countries and brought in a large amount of foreign property inputs. Cultural exchange is achieved through different channels. The main channels of ancient exchanges include envoys, trade activities, religious transmission, war capture and non-government exchanges.
