1. The meaning of paddle wheel
The meaning of paddle wheel is "paddle wheel". The following is a detailed explanation of the term: Definition: A paddle wheel is a mechanical device typically composed of multiple propeller blades that rotate around a central axis. Function: The main function of paddle wheels is to generate thrust or power through rotation, pushing equipment or ships forward. In ships, the propeller wheel is an important component of the propulsion system, which can convert the power of the engine into the propulsion of the ship. Application: Paddles are widely used in various types of ships, water transportation vehicles, and certain types of mechanical equipment, such as steamships, open ships, etc. In addition, in certain industrial fields such as hydropower and wind power, rotating blades based on similar principles are also used to convert energy.

4. Did sailboats actually be invented during the Three Kingdoms period???
As early as the Western Han Dynasty (about the 1st century BC), China began using oars. Rowing requires lifting the oars out of the water surface, which not only does virtual work but also wastes time. However, oars are continuous and use the principle of fish wagging their tails to move forward, so there is a saying of "one oar and three oars".. Europeans only began to consider using Chinese paddles as a replacement for their oars very late, but due to the invention of paddle wheels with better propulsion efficiency shortly thereafter, they did not consider using paddles anymore. However, it should be pointed out that the true inventors of the paddle wheel were also Chinese, more than a thousand years before Fulton. The Biography of Li Gao in the Old Book of Tang records: "Riding on two wheels, soaring in the wind and waves, as fast as hanging a sail mat." It can be seen that the Tang Dynasty (8th century AD) already knew to use paddles that could be stepped on by feet instead of paddles that could be moved by hand. Ships were called "vehicles and ships" in ancient China. According to existing records, the water battle between Yue Fei and Yang Yao in the Song Dynasty (12th century) was a major battle between vehicles and ships.
