Does it appear that Zheng he was traveling to unknown lands or to well established ports?

Zheng He primarily traveled to well-established ports rather than unknown lands. His voyages were meticulously planned and aimed at establishing diplomatic and trade relations with regions such as Southeast Asia, South Asia, the Middle East, and East Africa. The destinations he visited, such as Malacca, Ceylon, and the Swahili coast, were already significant trading hubs with established networks. His expeditions were more about reinforcing China's presence and influence in these regions than discovering new territories.
