简介：In ancient China, the size of a ship was calculated based on materials, that is, the amount of wood used. The more wood used, the larger the ship. A 400-ton warship has a displacement of about 70 tons, while a Dutch three-masted sailing ship has a displacement of 800 tons, one ship is equal to ten ships.
