Zheng He's voyage to the Western Ocean means that the Ming Emperor Judy ordered Zheng He, the eunuch of Sanbao, to anchor from Liujiagang, Taicang (now Liuhe Town, Taicang City, Jiangsu Province), and led more than 200 seagoing ships and more than 27,000 people to the Western Ocean and the Indian Ocean to visit more than 30 countries and regions including the Indian Ocean. He has been to Java, Sumatra, Sulu, Pahang, Zhenla, Guri, Siam, Bangra, Adan, Tian Fang and Zofari. It deepened the ties between the Ming Dynasty and Southeast Asian countries (now Southeast Asia), West Asia and South Asia.
Zheng He's voyage to the West was the largest in ancient China, with the largest number of ships (more than 240), the largest number of sailors and the longest voyage. Decades earlier than many European countries, it is a direct embodiment of the prosperity of the Ming Dynasty. Zheng He's voyages to the West far surpassed Portuguese and Spanish navigators for nearly a century, such as Magellan, Columbus, Da Gama and others. He is the pioneer of the "Great Navigation Age" and the only Oriental. He went to Africa 57 years earlier in Bidias.
