Lou Ship Lou Ship, a kind of deck building in ancient China is particularly huge, the ship is high and wide, and the appearance is like a building, so it is called "Lou Ship". Because the ancient water battles were mostly based on bow and arrow shooting, ship collision and jumping hand-to-hand combat, the size of the ship directly determined the number of sailors and warriors that a single ship could accommodate and the impact force of the ship, so the building ship served as the main ship of the water war in ancient times. However, due to the high height of the ships and the unstable center of gravity, they mostly served as the main force in inland water warfare.

The building ship is a kind of large warship with multi-storey buildings and offensive and defensive facilities, and the appearance looks like a building, so it is called a building ship. The large warship "Lou Ship" of the Han Dynasty is more than ten zhang high. During the Three Kingdoms, Soochow built a five-story warship that could carry 3,000 soldiers. The building ship not only has a majestic appearance, but also a spear on the ship, a tree flag, a strict guard, and a strong attack and defense, just like a water fortress.

A large warship that was equipped with the ancient Chinese navy. The ship was built with a heavy building, hence the name. Some serve as command ships. During the Spring and Autumn Period, with the development of warship construction technology and operational needs, warships with heavy floor-type superstructures appeared, collectively referred to as building ships. In 525 B.C., in the Battle of Wu and Chu Chang'an, the Wu army used the Wu throne ship, the large building ship Yu Huang, as the command ship. In 522 B.C., Wu Zixu, a doctor of the state of Chu, went from Chu to Wu, and in a question with the king of Wu, Wu said: "Those who build ships should be the building chariots of the army." This shows that the Wu and Chu Zhou divisions have been equipped with building boats.

In the Han Dynasty, the building ship entered a stage of great development. Emperor Wu of the Han Dynasty was preparing to conquer South Vietnam, so he built a large building ship, with a superstructure of 3-4 heavy, 10 zhang (27.6 meters) high, and could carry 1,000 people. Each heavy superstructure is equipped with cabins, women's walls, and battle grids, which serve as the support and protective facilities for soldiers and soldiers. There are many flags on the ship to make a strong reputation. The building ship became the main warship of the boat division, and thus also became the synonym of the boat division, so the Han Dynasty boat division became the building ship army, referred to as the building ship, or the ship army; The soldiers are called Lou Chuan Shi, and the leading officer is called Lou Chuan General. The person who oversees the building is called the building officer. During the Three Kingdoms period, the Wu Navy was equipped with 5-story building ships, such as "Feiyun" and "Gaihai" and other large building ships, which could carry 3,000 soldiers.

Since then, successive naval armies have used building ships as the main warships. During the Western Jin Dynasty, the building boat was equipped with a shooting rod. During the Eastern Jin Dynasty, Sun En and Lu Xun's maritime rebel army also had a boat division with large building ships as the main force. At the beginning of the Sui Dynasty, the boatmen were equipped with large building ships - Wuya ships. In the Song Dynasty, the technology of building vehicles and ships was applied to the construction of building ships, and the building ships equipped with as many as 24 cars were developed, and some of the ships were equipped with 6 shooting rods.

At the beginning of the Ming Dynasty, Zheng He's treasure ships in the West could cross the ocean for intercontinental voyages, which was the highest achievement of ancient Chinese building ship construction technology. At the end of the Ming Dynasty, Yuan Keli's Denglai naval army also widely used this kind of building boat.
