Humans have used windmills for more than 3,000 years. The earliest country in the world to invent and use windmills was ancient Greece. In traditional Chinese folk culture, windmills represent joy and auspiciousness, and mean peace and security in all seasons. There has been a proverb among Chinese people that "when the windmill turns, happiness comes". Windmill - represents bravery, diligence, enterprising spirit, loyalty, happiness, agility and love.

Ancient windmills developed from sails. They had 6 to 8 sail-like canopies, distributed around a vertical axis. When the wind blew, they rotated around the axis like a revolving lantern. This was called a revolving windmill. Due to its low efficiency, this kind of windmill has been gradually replaced by wooden cloth windmills with horizontal rotating shafts and other windmills, such as "vertical windmills", "automatic rotor windmills", etc.
