1.First voyage (1405-1407): From Nanjing, through the coasts of Fujian and Guangdong, through the Strait of Malacca, to present-day Vietnam, Thailand, Indonesia, Malaysia, etc., then continued to the west coast of the Indian subcontinent, visited Calikata and other places, and finally returned to China.
2.Second Voyage (1407–1409): This voyage extended further afield, including Sri Lanka and southern India, as well as parts of the Persian Gulf, such as the Strait of Hormuz.
3.Third voyage (1409-1411): The fleet again visited many parts of the Indian Ocean, including Sri Lanka and the east and west coasts of India, as well as the Maldives.
4.Fourth Voyage (1413–1415): This voyage further expanded to the Red Sea and the coast of East Africa, including present-day Somalia and Kenya.
5.Fifth Voyage (1417–1419): Zheng He's fleet again visited vast areas of the Indian Ocean, including ports in the Persian Gulf and the Arabian Peninsula.
6.Sixth Voyage (1421-1422): This voyage repeated the previous route, again visiting the countries of the Indian Ocean and the east coast of Africa.
7.Seventh Voyage (1431-1433): This was Zheng He's last voyage, and the route was similar to the previous ones, again visiting several regions of Southeast Asia, South Asia, the Middle East, and East Africa.
It should be noted that the details of these routes are somewhat controversial, as the records of the time were not entirely accurate, and some historical documents have been lost over time. The above information is based on available historical sources and scholarly research, but specific routes and places visited may vary.
