Windmills were originally invented by the Dutch to meet the needs of water power utilization and the mill industry. Although it is still a "national trademark" of the Netherlands, it is rarely used in practice. Of course we can’t bring back the big windmills from the Netherlands, but small souvenirs of the windmill models are ok and should be considered as souvenirs of your visit to the Netherlands. People often refer to the Netherlands as the "country of windmills". The Netherlands is a country in western Europe with a population of just over 10 million. Its real country name is "Netherlands". "Ned" means low, and "Lan" means land. Together they are called the "low-lying country". One-third of the Netherlands is only one meter above the North Sea, and nearly one-quarter is below sea level. It is truly the "Netherlands". The Netherlands is located in the Earth's prevailing westerlies, with westerly winds blowing throughout the year. At the same time, it is close to the Atlantic Ocean and is a typical country with a maritime climate, with sea and land breezes flowing all year round. This provides the Netherlands, which lacks water and power resources, with generous compensation for the use of wind power. Dutch windmills were first introduced from Germany. In the beginning, windmills were only used for grinding flour and the like. By the sixteenth and seventeenth centuries, windmills were of particularly great significance to the Dutch economy. It has: papermaking and other functions, and is known as the "Land of Windmills". The Netherlands has always been famous for its windmills. The place with the most preserved windmills is "Children's Difang". As a child, you read this story, right? A little boy saw a crack in the embankment and seawater seeping in. He was worried that the village would be flooded by the sea water, so he blocked the embankment with his fingers and saved the whole village... Today, 19 windmills are still preserved in this place, and some of them are still there. You can see Dutch women wearing traditional clothes. Until August 26, it is the "Windmill Day" in the Netherlands this year. Every Saturday, the windmills in Kinderdijf will rotate together, and some even open their interiors for visitors to visit. At that time, the Netherlands held a leading position in the world's commerce. Various raw materials were transported from various waterways to windmills for processing, including: wood from the Nordic countries and the Baltic countries, hemp seeds and linseeds from Germany, cinnamon and cinnamon from India and Southeast Asia. black pepper. In the suburbs of Rotterdam and Amsterdam, the great ports of the Netherlands, there are many windmills, sawmills and paper mills. As the Dutch people carried out large-scale land reclamation projects from the sea, windmills played a huge role in this arduous project. According to the local climate characteristics of humid, rainy and changeable wind direction, they carried out reforms on the windmill. The first step is to equip the windmill with a movable roof. In addition, in order to be able to face the wind from all sides, they installed the top of the windmill on rollers. This kind of windmill is called a Dutch windmill. The largest Dutch windmills are several stories high, with wind wings up to 20 meters long. Some windmills are made of a single piece of large oak wood. At the end of the 18th century, there were approximately 12,000 windmills in the Netherlands, each with 6,000 horsepower. These windmills were used to grind grain, coarse salt, tobacco leaves, press oil, roll woolen cloth, felt, make paper, and drain stagnant water from swamps. It is these windmills that continuously absorb and drain water, protecting two-thirds of the country's land from sinking and man-made threats from fish and turtles. Since the 20th century, due to the development of steam engines, internal combustion engines, and turbines, the ancient windmills that relied on wind power once became dim and almost forgotten. However, because windmills utilize natural wind power and do not suffer from pollution or exhaustion, they have not only been used by the Dutch people to this day, but have also become a new form of energy today, deeply attracting people. Currently, there are more than 2,000 windmills of various types in the Netherlands. The Dutch love their windmills and often praise them in folk songs and proverbs. Windmill buildings are always decorated as beautifully as possible. On every major festival, the windmill is decorated with garlands and hung with national flags and cardboard suns and stars.
