In the early Ming Dynasty, China was one of the most developed countries in the world.In order to transmit its national power and strengthen contacts with other countries,Emperor Chengzu sent Zheng He to the Western Ocean many times.In 1405,Zheng He embarked on his first voyage.His fleet was composed of more than 200 ships and carried over 20,000 men,including sailors,soldiers,technical personnel,interpreters etc.,and large amounts of gold and silk to be used for trade and as gifts.The round trip took two years.Some of the countries Zheng He visited dispatched envoys bearing tributes to the Ming court on his ships.Zheng He's voyages were a great feat in the world's navigation history.Today,there are still many buildings in Southeast Asia dedicated to his memory.
