Master Zheng He has many kinds of ship types. According to historical records, there are sea otters, seagoing ships, sea breeze ships, seagoing ships and treasure ships. According to the characteristics of ship types, there are blessing ships, bird ships, sand ships and wide ships. According to the propulsion mode, there are 9 masts 12 sails, 3 masts and 5 sails or 8 paddles and 6 paddles. The above-mentioned "sea boat", "bird boat" and "3 masts and 5 sails" are completely consistent with the ship types of Zhoushan "Green Eyebrow" ancient sailboat. From 1405 to 1433 A.D., "Green Eyebrows" went to sea with Zheng He's huge fleet, made seven voyages to the Western Ocean, and visited more than 30 countries and regions in Asia and Africa, which not only opened up the great discovery of the world's oceans, but also set a peaceful model for the Chinese nation to be good neighbors, good-neighborly diplomacy and common development. It can be called the pinnacle of the Chinese nation and even the history of human navigation.
Treasure ships are the largest seagoing ships in Zheng He's fleet. It is the shipbuilding achievement of China shipbuilders in the Ming Dynasty combined with previous dynasties, and the sailing history of China made by them is also the largest wooden sailboat in the world. Its position in the fleet is equivalent to the flagship of today's big fleet and is the main ship of the whole fleet. The five ship names "Qinghe, Wellcome, Changning, Anji and Qingyuan" mentioned by Zhu Yunming in the article "Going to the Western Seas" in the past are probably such treasure ships. The giant treasure owners in Zheng He's fleet were built in Nanjing Treasure Shipyard.
