.What is the most valuable impression of Zeng He Voage?

With more than 27,500 people aboard, it was the greatest fleet with the largest crews the world had ever seen. Carrying cargoes of porcelain, silk, tea, and numerous other treasures, the fleet navigated the South China Sea, passing through the Strait of Malacca, and traversing the Indian Ocean to arrive at countries on the coasts of Asia and Africato the Western Seas, his fleet consisted of more than 100 ships, with 62 large and medium-sized ships forming the main body. Crews and other personnel added up to more than 20,000. Columbus' fleet had only three ships and an 88-member crew. Obviously, Zheng He's fleets were unparalleled during his time in terms of size, navigation technology, organization and amenities, in order to be capable of making those successful long trips.Compared with these explorers, Zheng He's voyages took place much earlier and on a much larger scale. On each of the seven voyageswith crews totaling more than 100,000 people, left China for further voyages to the Western Seas and arrived in more than 30 countries along the way – "Western Seas" being the term used in ancient China to refer to the regions west of the South China Sea. In West Asia, they visited the holy city of Mecca; in Africa, they reached as far as the port of Beirameters, equal to the size of half a football field. The ship had nine masts with 12 sails. Its iron rudder needed more than 200 people to lift. The large ships of Zheng He's fleet would still look extraordinary even today.Zheng He's ships were also constructed with advanced technology and craft. A large-size ship in the fleet was 150 meters long, 60 meters wide and 12 meters deep. It had a cargo capacity of about 1,000 tons, with four levels to house more than 1,000 crew and passengers. The foredeck had an area of 9,000 square.
