The historical significance of Zheng He's voyage to the West: Zheng He's fleet traded with western countries on an equal footing. Wherever the fleet went, most of them were warmly welcomed. For example, on the first voyage to Zhancheng, the king and his subjects greeted him with gongs and drums. The fleet exchanged gold and silver treasures, silk and celadon tableware for jewels, spices, medicinal materials and exotic foreign objects from all over the world. Zheng He's voyages to the West promoted the economic exchanges between China and Asian and African countries. When Zheng He went to the Western Ocean, he invited countries to visit China. During the Yongle period, kings, queens, envoys and caravans from Bonai, Manzega, Sulu and other countries came to Nanjing and Peiping in China in an endless stream, sometimes with more than 500 people accompanying them. The Ming government hosted a banquet and presented many gifts, which were displayed in the Wenhua Hall. King Sulu died of illness in Dezhou, Shandong Province on his way back to China, and Ming Chengzu ordered him to be buried in northern Texas with a royal ceremony (let students see the tomb of King Sulu, located in Beiying Village, the northern suburb of Dezhou today). This is an outstanding example of the development of friendly relations between China and foreign countries in the Ming Dynasty. Zheng He's voyages to the West promoted the friendly exchanges between China and Asian and African countries. Zheng He's voyage to the West further promoted the flow of China people to Nanyang.
