1. Fengwa has done so many things for people in obscurity. The first thing is the most common thing in life, which is people's washed clothes. Fengwa will help people dry them.
2. The wind doll can also bring rain to people. It can blow away dark clouds. The most important thing is that it can exchange dry and cold air with warm and humid air over a large area. Able to regulate air temperature appropriately.
3. The wind doll has silently helped people a lot. It can also generate electricity for people. The wind doll can really make all the blades of the windmill rotate quickly, and then people can increase the speed.
4. Also, the weather in summer is so hot. Only the wind doll can help people blow cool wind to people, and it can also blow away those pesky flies at the same time.
Extended information:
1. Strong winds blow up a lot of sand and dust on the ground and roll it into the air, making the air extremely turbid and the horizontal visibility is very low. Strong winds carrying fine sand and dust destroyed buildings and public facilities, causing casualties of people and animals.
2. Typhoons always bring all kinds of damage. They are sudden and destructive and are one of the most serious natural disasters in the world. The heavy rains and tsunamis it brings are powerful and destructive.
3. It is a strong, small-scale air vortex, generated by strong convective movement of air under extremely unstable weather. A strong wind accompanied by high-speed rotating funnel-shaped cloud columns. The wind speed near the center of a vortex can reach 100ms to 200ms, with a maximum of 300ms, which is several times greater than the maximum wind speed near the center of a typhoon. It is extremely destructive.
4. If we don’t pay attention, the things we need will be blown away without a trace. When the wind gets angry, it will blow away many things, even doors, windows, houses, crops, and flowers and fruits. Meng Haoran "The sound of wind and rain at night can tell how many flowers have fallen." Du Fu said in "The Song of Thatched Cottage Broken by the Autumn Wind" that "the high autumn wind howls in August and rolls up the triple thatch on my house."
The wind can help people do the following things:
1. Making food: Wind can accelerate the loss of water, such as air-dried meat, air-dried fruit pulp, etc. Xinjiang raisins are a typical dried food.
2. Blow dry clothes: Wind can accelerate the evaporation of water on clothes, speed up water loss, and make clothes dry faster.
3. Wind energy generation and irrigation: The wind can drive the windmill blades to rotate, and then increase the speed of rotation through the speed increaser to prompt the generator to generate electricity. Wind power is pollution-free, clean energy, and renewable. Ancient people also used windmills to water crops.
4. Help fruit trees and crops to bloom and bear fruit: Wind can blow away pollen, fertilizing fruit trees and crops to bloom and bear fruit.
5. Power-assisted sailing ship: In ancient times, ships without a power system relied on wind energy to move, which greatly reduced the voyage time.
6. The wind will blow away the dark clouds and haze: When the dark clouds block the sun, it is the wind that drives them away, allowing the sun to fill the earth again. When pollution is serious in winter, it can blow away the smog.
7. In the hot summer, the wind brings us coolness and drives away mosquitoes and flies.
8. Bring rainfall: Wind can blow clouds, promote the exchange of dry, cold and warm and moist air, and adjust the temperature and humidity of the air. This is what the ancients said: "The clouds turn into rain, and the dew turns into frost." Wind can send clouds and rain to distant places, completing the water cycle on the earth. In summer, warm and moist air blowing from the ocean brings abundant rainfall.

Wind is also a "double-edged sword". It can both Helping people will have a negative impact on people's lives.
It can spread pathogens and spread plant diseases; high-altitude winds are the meteorological conditions for locusts and other pests to migrate long distances; strong winds can cause mechanical scratches on leaves, lodging of crops, broken trees, and falling flowers and fruits, affecting yields. ; Strong winds also cause soil erosion, sand dune movement, and damage to farmland. In addition, wind has greater dangers. Blind reclamation in arid areas will lead to land desertification; strong winds and snowstorms in pastoral areas can scatter livestock and aggravate frost damage; some special properties of local winds often cause wind damage; salt-laden wind blowing from the sea Sea tidal winds, high-temperature and low-temperature foehn winds, and hot and dry winds all seriously affect the flowering and fruit setting of fruit trees and the grain filling of cereal crops.
In order to reduce the damage caused by wind, some measures can be taken to prevent wind damage. For example, wind-resistant varieties that are dwarf, lodging-resistant, and friction-resistant are often cultivated. In addition, building windbreaks and setting up wind barriers are even more effective methods of wind protection.
