Based on historical records, it appears that Zheng He was traveling to well-established ports. Zheng He led several expeditions throughout Southeast Asia, South Asia, and East Africa, visiting ports in places such as India, Arabia, and Somalia. He was also known to visit places that had already been explored and traded with by the Chinese, such as the Maluku Islands and the Philippines. While Zheng He's expeditions were extensive and covered great distances, they were primarily focused on establishing and maintaining trade relationships with existing ports, rather than exploring unknown lands.
