In ancient times，silk from China found its way overland to India，the Middle East，and Rome，along what became known as the Silk Road. A trading route across thesea was also extended along the coasts of the Indian Ocean，centered around Ceylon（now Sri Lanka）. Here，merchants from China and many other places met to negotiate trade deals，which also led to more awareness of each other’s cultures. Over the centuries，further trading allowed more exploration of the regions to the west of China，as recorded in Du Huan’s Record of My Travels in the eighth century.

Later，the Ming Dynasty further developed relations with these regions.Between 1405 and 1433，seven large fleets sailed west on voyages of trade and exploration.These fleets were a sight to behold and were in a league of their own at that time. Under the command of Zheng He，they set sail from the South China Sea across the Indian Ocean to the mouth of the Red Sea，and then to the east coast of Africa. African royal families sentgifts such as giraffes as gestures of friendship in return for gold，silk，and spices. Although China withdrew from further expeditions after1433，these land and sea routes remained active channels between othercultures for centuries.

Although the ancient sea routes of ZhengHe have been travelled many times，there are still many other places left to explore.
